===Fame===
*When footage of Humungousaur holding up the bridge from All That Glitters is shown on TV, he does not grow his stegosauride features despite doing so in the original episode.
*When Ben, Gwen and Kevin enter Jimmy's room, Kevin is taller than usual. This error occurs again when they come out of the water.
*When Jetray saves the pilot and says "Gotcha!" his mouth doesn't move.
*During Chromastone's transformation sequence, Ben is wearing the Omnitrix.
*Ben as Chromastone says that he wasn't sure the transformation was still available to him. However, Sugilite had informed him that the form was still in the Omnitrix in The Secret of Chromastone.
*Chromastone forms an energy ball, but in the next shot, the energy is shapeless.
*When Ben wakes up after being defeated by Bivalvan, Rozum has green eyes.
*When Ben gets out from the water, his shoe is miscolored.
*Towards the end of Ultimate Spidermonkey's transformation sequence, the muscles on the right of his body are gone for a brief moment.
*When Ben as Ultimate Spidermonkey wraps Bivalvan in webbing, his knee sticks out, but when it shows him fully wrapped up, his entire body is covered in webbing.
*After Ben reverts from Spidermonkey, his eyes glow pink for a moment. This is an animation error, as they are meant to be red.
*When Ben is about to go to school, his backpack is brown. Then, for one shot, his bag is cyan.
*Aggregor has six horns instead of four.

*When Kevin absorbs metal from a manhole cover, he is covered in stone. This error occurs again when he absorbs metal from a pipe.
*Sensitive Ben is able to call the other two Bens despite them sharing the same phone number.
*When Sensitive Ben calls Film Fan Ben and Rude Ben, it is nighttime outside the museum, but the tennis match is being held during the daytime. Furthermore, the Sumo Slammers movie started at 2 PM, but when Film Fan Ben leaves the cinema, it is nighttime.

===Too Hot to Handle===
*The closed captions on the Ben 10 Ultimate Alien: Escape from Aggregor DVD misspell "Taydenite" as "taedenite".
*In one shot, Kevin is shorter than usual.
*Even though there is a sound of P'andor's containment suit getting pierced, the suit is still intact until Kevin is tricked into actually opening it.
*When Humungousaur goes Ultimate, the flash of light is blue instead of green.
*When Water Hazard goes inside the nuclear reactor, he turns the Ultimatrix symbol until it's sideways. However, when he hits it to turn into Big Chill, the symbol is no longer sideways. Also, before he hits it, the symbol is no longer red (indicating radiation) even though P'andor is still there. It remains this way when Big Chill fights P'andor.
*Kevin absorbs P'andor's green armor, but after the scene changes his body becomes silver.

===Fused===
*When Ben jumps off his bed after being attacked by Ra'ad, his left foot only has four toes.

*Just like in Escape From Aggregor, Ben is able to safely use the Ultimatrix to transform even though Ra'ad is present and it hasn't scanned him yet.

===Hero Time===
*The crowd standing at both the book signing and at the party changes from a cluster line into a single file line.
*When Ben approaches the thugs, the Ultimatrix dial is facing the wrong way. Also, the dial doesn't pop up, nor does a hologram appear. 
*When Ben becomes Spidermonkey, the fans are standing in front of the cordon, even though they were standing behind it before the fight.
*Spidermonkey flies on top of the building across the street. This is actually the same spot where Captain Nemesis puts on his armor, but he is not seen.
*Various other errors occur during the first fight:
**Although both of Jennifer's bodyguards are shot and thrown backwards, they disappear throughout the fight and even when Jennifer kisses Ben.
**The fans at the book signing appear and vanish throughout the fight.
**Jennifer and the thug who keeps her at hostage constantly vanish and appear.
**The guns vanish after the thugs are disarmed and beaten.
**The Darkfall poster on the door appears and vanishes throughout the fight.
*When Spidermonkey gets hit and flies backwards, there's an ice cream store, but when he moves the collapsing streetlamp away from the fans, the store is missing.
*Right after Kevin knocks one of the thugs out, Spidermonkey is fighting one of the thugs on the right side of the red carpet. Then, when Spidermonkey throws him into other thugs and trapping them in the web, the fight takes place on the left side of the red carpet.
*Spidermonkey's additional positions before and after his confrontation with the thug holding Jennifer is inconsistent. After trapping the thugs using his web, they are in the center of the red carpet. Then, when Spidermonkey jumps backwards, he should have landed on the left side of the red carpet. Instead, when sliding backwards, he is in front of the main entrance again but is not on top of the defeated thugs. Then, when Captain Nemesis arrives, Spidermonkey can be seen on top of the defeated thugs before jumping off.
*It's impossible for Jennifer to run towards Ben in a straight line, since she was at the main entrance, while Ben was on the right side of the red carpet meeting Captain Nemesis.
*Gwen and Kevin rush up to the entrance to knock one of the thugs out. However, when Jennifer kisses Ben, Gwen and Kevin are standing back in their original spot in line as if they haven't left.
*Kevin mutes the volume on the TV when he, Gwen, and Julie watch the news about Ben and Jennifer. However, when Ben arrives and watches Harangue's news, the volume is automatically unmuted.
*When Gwen, Kevin and Julie watch the initial news coverage on Ben and Jennifer, Gwen eats food from a paper bag, but when Ben arrives, the bag disappears.
*When Kevin says, "I do" before Gwen hits him, his face and hand are merged.
*When Jennifer talks to Ben by the helicopter, Ben's jacket stripes are on both sleeves.
*When Jennifer says, "Ready for the party?" to Ben, Gwen and Kevin vanish when the camera moves from Julie to Ben.
*When Ben is at the party, his jacket stripes are on the wrong side.
*It stops raining within a second when Simons speaks with Harangue.
*When Jetray dives, his chest stripe is yellow.
*Before Armodrillo changes back, he is standing behind Captain Nemesis, but when Ben appears, he is suddenly in front of Nemesis.
*Ben says that he defeated ten of Computron's minions, but if counted, he only defeats five. In fact, there were only about five of them in that scene.
*When Jennifer begins hosting for the friendly contest, her shorts are black. This occurs again when Captain Nemesis fires a fire blast at Gwen's mana shield.
*Humungousaur's feet appear before Ben transforms into him.
*When Ben and Nemesis are having their race one of the placards the fans are holding reads "I <3 BEM".
*When Captain Nemesis wins the race, the audience is reused three times.
*The bridge vanishes when Captain Nemesis beats Rath in the race.
*During the competition, in one shot, the "N" on Captain Nemesis' chest is miscolored.
*After Captain Nemesis loses the competition, one of the audience members doesn't have a face.
*When Ben enters the Nemesis Tower, his jacket stripes are on his left sleeve instead of his right sleeve.﻿
*During Ultimate Humungousaur's transformation sequence, Humungousaur's back is light brown.
*Ultimate Humungousaur is supposed to be able to launch missiles out of the blaster scopes he can unveil in the knuckles of his hands. Instead, when he uses them, red laser bolts are fired rapidly out of the top scope as his hands spin as if they were the cannon barrels for revolvers.
*When Captain Nemesis shoots a rope at Ultimate Humungousaur's arm, the rope on his arm disappears for a split second and reappears in the next shot.
*When Captain Nemesis pulls the rope he wrapped around Ultimate Humungousaur's left wrist, Ultimate Humungousaur's eye is colored red, and the portion above it is mistakenly colored green.
*When Nemesis flies towards Ultimate Humungousaur, his horn is green.
*Ben arrives at Nemesis Tower alone. However, after rescuing Julie, Gwen and Kevin unexpectedly appear to rescue Jennifer, without explanation as to how they knew where Captain Nemesis was.
*Right when Water Hazard takes his first swing at Overlord, the "N" on his chest is missing.

===Map of Infinity===
*In many shots, the black outline around Humungousaur's lips is missing.
*When Humungousaur lifts Ultimate Aggregor by the chest, Ultimate Aggregor boasts about having Bivalvan's armor, even though Bivalvan's armor is only present on his legs.
*When Humungousaur stands over Ultimate Aggregor, the lines on his lower stomach overlap past his stomach.
*When Humungousaur first charges Ultimate Aggregor, Aggregor is down in one shot and standing in the next.
*When Aggregor blasts Gwen, she doesn't have a face.
*At one point, the sound effect of Kevin covering his arms in armor is played, even though his arms are already covered.
*When Azmuth inspects the Ultimatrix, the dial is sideways and the rim isn't raised.

*The Necrofriggians suddenly appear on the bridge.
*When Ben transforms into Big Chill, the Ultimatrix symbol's colors are reversed.
*When Big Chill talks to Gwen, the green and light green of his eyes are reversed. Furthermore, the rim of his Ultimatrix symbol is white.
*When Big Chill talks to one of the Necrofriggians, his Ultimatrix symbol is missing. This error occurs again when he tackles one of them.
*When one of the Necrofriggians turns intangible, the effect is applied to the spaces outside his antennae and wings, rather than the antennae and wings themselves.
*When two Necrofriggians tackle Big Chill to the ground, they make an impact instead of phasing through it.
*When Ben first turns into Ultimate Echo Echo, he grabs his shoulder disks. Yet, after he takes them off, the right shoulder disk is still there, then in the next shot, it's gone. His fingers also turn blue during this scene.
*When Ultimate Echo Echo attacks the first Necrofriggian, he disappears for a split second.
*When Ultimate Echo Echo attacks the second Necrofriggian, his left eye misses its stripe.
*When Ultimate Echo Echo knocks out an intangible Necrofriggian, he lays on the ground instead of phasing through it. In the same scene, part of Ultimate Echo Echo's chest is grey.

*When the wall behind the Esoterica soldiers explodes, the energy orbs around their hands do not crackle like they are supposed to for a few frames.
*In one shot, one of the five Plumbers has purple eyes instead of black eyes.
*Gwen refers to Dagon as "the dragon" when talking to Winston. It is unknown how she obtained this information, as the drawings in the Flame Keepers' Circle's headquarters depict him as a squid-like creature.
*When Kevin lifts Winston off the ground, Winston's legs are cut off.
*When Sir Driscoll shoots the team, his hand/gun does not move. He fires three shots to exactly the same point, but the trio still collapse.

*When Kevin pilots the Rustbucket 3, in one shot, his hands are behind the steering wheel.
*When Kevin absorbs a metal helmet, he becomes a different color. He switches between the right and the wrong color in several shots.
*When Ben is defeated as Eatle, he lands on his back. But when he reverts to normal, Ben is on his stomach.

===Solitary Alignment===
*When Sir George took Ascalon in the previous episode, Ben yelled "Stop him!", but when the scene is replayed in this episode, Ben is silent.
*When George enters the other side of the seal, its pattern is missing.
*When Azmuth says to George "You think I can't?", the black middle stripe on his suit is gone.
*When Ben transforms into Fasttrack, the Ultimatrix's core doesn't pop up. 
*When Fasttrack shouts his name, his mouth doesn't move.
*When Azmuth appears on Primus, he is bigger than usual. This error occurs again when he brings the team to Earth in the Middle Ages.
*When one of the Forever Knights slices a Lucubra in half, the Lucubra's shadow overlaps the fire in the background for a moment.
*When Kevin gives Gwen a lock of George's hair, his overshirt overlaps his undershirt for a moment.
*When George deflects Ultimate Humungousaur's missiles with his sword, the effect is more akin to deflecting bullets than explosive projectiles.
*The end credits misspell Fasttrack's name as "Fastrack".

===Inspector #13===
*After Inspector 13 opens the garage door, Kevin's car appears next to him.
*When Gwen appears in Kevin's garage, she has a sweat band on her left wrist. When Kevin tells her to power up, the sweatband is gone.

*After the ship lands, the net disappears, and not only does an Echo Echo disappear, but Julie is also on their side. In the next shot, the second Echo Echo disappears.
*When Inspector 13 lifts Ben's left arm, the Ultimatrix's dial faces the wrong way.
*In one shot when Julie punches the ship, the door is gone.
*Inspector 13 says "No one has seen us and lived" although he knew Kevin and Julie had tried fighting him and survived.
*When Ben is strapped to the torture table, the position of the shackle on his left hand keeps changing. For a while, the Ultimatrix is partially inside the shackle, then it comes out and goes back in.
*Several times on Inspector 13's ship, Kevin's armor changes color.
*In one shot when Diamondhead is falling, the shards on her back are missing.

*When Gwen as Rath tears off the head of the Techadon Robots, there are four fingers on her head.
*The end credits misspell Jetray's name as "JetRay".

===Enemy of My Frenemy===

*In one shot, Ben's jacket stripes are on both sleeves.

*One inmate has an orange stripe on his chest instead of white.
*In one shot when Ben and Gwen are in the Mark 10, Gwen's stockings are missing.
*When Ben nearly hits the truck, the Ultimatrix symbol is missing from the wheels of his car.
*When Jennifer talks to Carl Nesmith in the limo, first her arm is under his arm, but in the shot after, her arm is above his.
*In one shot, the white stripe on Nesmith's chest is on the right side.
*For some reason, Goop's Anti-Gravity Projector is once more able to pass under the door, the first time being in Vengeance of Vilgax: Part 2 and the second time being ...Nor Iron Bars a Cage.
*Ben says he accidentally melted the doorknob as Goop, but the doorknob is still intact.
*Gwen says "Remember, keep it quiet". After that, she says "That's your idea of quiet?" even though Goop did not actually make any noise other than the sizzling of the doorknob melting.
*When Ben is fighting Carl, half of Carl's mustache is briefly skin-colored.
*When the Ultimatrix user gets sufficiently hurt or knocked out, it would revert them back. However, when Clockwork falls unconscious, the Ultimatrix does not revert him to human.

===The Eggman Cometh===
*When Natalie is cooking in the kitchen, the bowl she uses to mix ingredients changes size between shots.
*Melinda stops speaking on the radio once Gwen opens the door to the kitchen.
*When Gwen talks on the phone, Kevin has six cartridges instead of seven.
*When Kevin is teasing Ben when he wants to continue their training, when Ben raises his Ultimatrix arm up, the Ultimatrix is overlapping his jacket.
*In Kevin's car, Ben moves from the left to the right and then to the middle.
*In one shot, Kevin is not wearing a seatbelt.
*When Ben scrolls through his aliens before turning into Juryrigg for the first time, the aliens' holograms face away from him. This error occurs again before Ben turns into Fasttrack for the second time, and Juryrigg for the second and third times.
*Given the floorplan of Gwen's house, it is actually impossible for the kitchen to exist in it. The Pterodactyl can be seen running into the street from the wall to the right of the refrigerator. It can be inferred that the kitchen should be at the front end of the house. However, the window seen is too small to match up with the window seen in exterior shots of the house, and if that were to be the case, the window above the sink would look into the entranceway of the house rather than outside.
*When Clockwork views the past in Gwen's house, Natalie does not say "What is it, honey?" like in the original scene. Furthermore, her line "Okay, but don't eat any peanut butter sandwiches" is cut, as she just says "sandwiches". Melinda's voice is also not heard from the radio.
*When the trio leave the police station, they leave the door open, but in the next scene, the door is closed.
*When the scientist is talking, Ben's jacket stripes are gone.
*In the old steel mill, before Ben becomes Big Chill, the garage-type door behind him is open, but after he transforms, the door is closed.
*Before Ben becomes Big Chill, his hologram doesn't appear on the Ultimatrix.
*When Gwen blasts the wall behind Dr. Animo, the area behind it is shown to be outside, but in the next scene, it is shown to be another room.

===Couples Retreat===
*When Ben reads the page from Gwen's spellbook and shows it to Gwen, it is empty.
*When Kevin and Ben talk about Charmcaster beating Darkstar, the thickness of Ben's shoulder stripe changes.
*Gwen's spellbook is missing the gold outline on the cover.
*When Jetray talks in one scene, he only has three top teeth.
*It seems strange that Darkstar is unable to absorb electricity during his second fight with the team when he was seen safely absorbing some electric energy without difficulty right before the fight.
*In Ben 10,000 Returns, Ben 10,000 used the "Contego" spell to conjure a mana shield, but in this episode, Gwen uses the same spell to drain Darkstar of his powers. 
*There is no logical reason for Gwen to have gone out with Darkstar more than once, as she claims.
*When Diamondhead creates a crystal shield, his neck is green like his crystals.
*Gwen is somehow able to teleport the team out of Legerdomain, when the Door to Anywhere is the only way in or out of the dimension.
*At the end of the episode, Charmcaster's collar is entirely black.
*The end credits misspell Jetray's name as "JetRay".

===Night of the Living Nightmare===
*The underside of the Ultimatrix is drawn differently between shots.
*When Ben fights the Dream Eater, the Ultimatrix's dial is turned.
*When Four Arms catches the streetlight thrown by the DNAlien, it goes through his body.
*In one shot, Vilgax's left fingers are green instead of gold to match the Shield of Seagle.
*Goop changes directly to Ultimate Spidermonkey without first turning into Spidermonkey.
*The design on Lodestar's back is different in one shot.
*The soles of Eatle's feet change from purple to silver between shots.
*Julie throws Eatle to the sky diagonally, but he falls back to where he was thrown, instead of falling further away.
*In one shot, the door on Kevin's car is grey instead of green.
*When Ultimate Kevin is holding Ben by his wrist, Brainstorm's arms are discolored for a split second.
*When Ultimate Kevin reverts to Kevin, his clothes are intact despite his shoes and shirt vanishing when he turned into Ultimate Kevin.
*When Ben smacks the Ultimatrix to turn into Swampfire, the dial isn't pushed down.
*When Albedo writhes on the floor at the end of the episode, the shadow cast by his pant leg is under the spilled smoothie, instead of over.
*Albedo's nightmare has several errors:
**At first, Cannonbolt is behind Diamondhead, but then he is in front of him.
**Four of Diamondhead's six back shards are smaller than usual, looking more like stubs than shards.
**Lodestar is much bigger than usual, being taller than Armodrillo and almost as tall as Ultimate Humungousaur, although the latter is also smaller than usual.
**Ultimate Swampfire's face is different, being more hexagonal in shape, his facial pattern is reversed, and it seems to overlap the shells on his back rather than being separated by his bark-like skin.
**Upchuck is missing most of the stubs on the back of his head, as only one is visible from the angle he is seen from.

===The Beginning of the End===
*When Ben is about to transform into Four Arms and Goop, the Ultimatrix's core pops up without Ben activating it.
*In the establishing shot of Area 51, there are no Forever Knights, but there is an army in the next shot.
*When Four Arms sits, his underwear is red. Kevin's car is also missing in this shot.
*Before Four Arms reverts to Ben, he is taller than usual.
*Clockwork's hologram faces Ben at an angle.
*When Clockwork showed the past in The Eggman Cometh, Gwen and Natalie spoke backwards, but when Clockwork shows the past this time, Conduit Edwards' mouth moves without any audio being heard.
*The CGI models of the Forever Knights do not have the infinity symbol on their chest.
*During the battle between the Forever Knights and the Esoterica, one Forever Knight pops into frame out of nowhere.
*When the Forever Knights charge towards the Rustbucket 3, they are smaller than usual. Furthermore, there is a layering error, where one Forever Knight runs under the Rustbucket's wheel.
*Goop's hologram faces away from Ben.
*When Goop is cut into half by the Forever Knights, even his Ultimatrix symbol is cut.
*When Winston is hit by Conduit Edwards' energy blast, there is no crater. However, when Sir George goes to his side, Winston lies in a crater.
*When Fasttrack punches an Esoterica soldier, two soldiers are shown for a frame.
*When Heatblast lands in the depression he created, the hole is about his waist level. However, in the next shot, it is at his knee and in the shot after that, it is almost at his chest.
*The end credits misspell Dagon's name as "Daigon".

===The Ultimate Enemy: Part 1===
*Two Esoterica soldiers are partially transparent in some shots.
*When the wave turning humans into Esoterica reaches the tennis stadium, all the people should have transformed at once. However, Julie's opponent becomes an Esoterica and after about three seconds, the crowd follows suit.

*In one shot, Vilgax's shoulders are bigger than they should be.
*The end credits misspell Dagon's name as "Daigon".

===The Ultimate Enemy: Part 2===
*In the previous episode, Dagon said "At last" before he physically appeared, but during the recap at the beginning of this episode, he says it after he appears. Furthermore, Juryrigg faces the opposite direction compared to the previous episode.
*Way Big and Wildmutt's holograms face away from Ben.
*Before Ultimate Way Big pulls Dagon from the sky, his left shoulder is colored blue. This also occurs with his hands before he changes back.
*When Dagon reverts to his regular form after defeating Ultimate Way Big, he turns transparent, during which there is an error where the division between his two layers is visible.
*The river that Ultimate Way Big battles Dagon in covers his feet, but when he reverts to Ben, it is much shallower.
*Ultimate Way Big changes back into Ben without changing back into Way Big.
*When Ben transforms into Ultimate Wildmutt, he only has three nostrils instead of four.
*When Kevin absorbs metal, there is a layering error, where some of his human skin is visible.
*When Ultimate Wildmutt attacks the Esoterica, his lips are the same color as his skin.
*In one shot, after Ultimate Wildmutt reverts to Ben, Kevin's body is not covered in metal.
*After Ben gets up after reverting from Chromastone and Sir George had been turned to dust, Gwen appears noticeably taller than Ben.
*After Vilgax absorbs Dagon's power and ascends to the sky, his mouth initially does not move when he speaks.

*Gwen's height relative to the chair in the Plumber base changes between shots.
*In one shot, after Vilgax destroys the Plumber base, Gwen's helmet is gone.
*When Ben raises Ascalon against Vilgax, the Ultimatrix can be seen poking out of his sleeve. However, when the sword armors him up, the Ultimatrix can't be seen, despite the fact that it clearly would be.
*When Ben is in the midst of being tempted by Vilgax into using the power of the Ultimatrix, Ascalon, and Dagon to rid the universe of evil, Julie suddenly is able to help Gwen and Kevin talk him out of it, despite not being present when the conversation started and shouldn't know what's happening.
*Strangely, when Vilgax is stripped of his powers, he has his regular clothes back on, which is impossible as it was shown in The Final Battle: Part 2 that he shed his clothes when he transformed into his true form.
*When the camera shows Ben thinking about what to do with all the power he has, Gwen is seen once again without her helmet on.
*The flashbacks from previous episodes shows scenes that Ben wasn't present in despite said flashbacks supposedly coming from his mind.

*In one shot, Rath has five fingers. Additionally, in one frame after saving Diane and her cameraman, one of Rath's eyebrows is colored white, similar to his reboot counterpart.
*When Rex is first holding Six, his glasses are off and his eyes are closed, then when Rex tells Ben it was all his fault, Six has his glasses on.
*Before Ben transforms into Big Chill, the containment unit is much wider than it should be.
