The Final Battle: Part 2

The Final Battle: Part 2 is the twentieth and final episode of the second season of Ben 10: Alien Force, and the forty-sixth and final episode overall.
==Synopsis==
Ben is defeated by the pair and gives up the Omnitrix to save himself and his friends. Powerless, Ben goes aboard Vilgax's ship and faces off with Vilgax to stop his invasion of Earth in their final battle!
==Plot==
Starting from where the previous episode left off, Ben has given Vilgax the Omnitrix in exchange for the lives of his teammates. Max arrives and fends off Vilgax and his Bioids, delivering Gwen her spellbook, which she uses to teleport the team away. Albedo, as Ultimate Humungousaur, demands that Vilgax give him the Omnitrix as per their deal. However, Vilgax refuses and dons the Omnitrix. He reveals that his Bioids are programmed with blank DNA synchronized to the Omnitrix and that when he activates it, all of his Bioids transform into the selected alien. Vilgax transforms his Bioids into an army of Humungousaurs, who attack Albedo. In spite of defeating hundreds of them, Albedo is eventually overwhelmed when the Ultimatrix times out, and Vilgax captures him.
The team watches Albedo's defeat from a Plumber security camera in the Rustbucket 2. Ben, blaming himself for losing the Omnitrix to Vilgax, loses hope, angrily orders Max to stop the Rustbucket, and runs off into the woods. Kevin suggests leaving Ben behind, stating saving the world is "Not a job for quitters", causing Gwen to admonish him for giving up on Ben. Max advises Gwen and Kevin to leave him alone for a while, but Gwen disagrees and follows Ben into the forest.
She offers him his jacket, but he discards it, claiming it belongs to a hero. Even when Gwen reminds him of all the times Ben was able to help others without the Omnitrix, Ben disagrees, feeling that he's nothing without the Omnitrix. Gwen leaves after expressing faith in a hopeless Ben, who contemplates on what to do next. Unable to bring himself to give up, Ben angrily calls out to Azmuth for help. Azmuth arrives and reminds Ben that he found the Omnitrix by accident as it was intended for Max as Ben was only able to wear it for being his grandson in a close genetic match. Just as Ben states that Azmuth should've taken it from him, Azmuth tells Ben that he was planning to, but Max convinced him otherwise as he praises Ben for his bravery and ingenuity with or without the Omnitrix. He then scolds him for disobeying his instructions and hacking the Omnitrix. Ben doesn't argue, bringing up how he turned Kevin into a monster and wistfully asks Azmuth how to defeat Vilgax. Azmuth notes that it's difficult to win without the Omnitrix, which Ben agrees, getting an idea and reinvigorates him. He heads back to the Rustbucket, claiming he has a plan.
On Vilgax's ship, Vilgax overlooks the Earth and plans his invasion while the imprisoned Albedo looks on and mocks him. Gwen teleports the team onto the ship, and Vilgax quickly surrounds them with his Bioids, demonstrating their power by transforming them into Diamondhead, Lodestar, and Spidermonkey. Ben commands Vilgax to surrender the Omnitrix, but Vilgax refuses, mockingly asking why he would give the device up. In response, Ben activates the Omnitrix's voice command mode and orders it to self-destruct in 30 seconds. Vilgax, believing Ben to be bluffing, transforms his Bioids into Swampfire in order to destroy Ben and the team. Moments later, the Omnitrix self-destructs, knocking Vilgax unconscious and permanently deactivating his Bioids. As Ben recovers the remains of the Omnitrix, Kevin is struck with a sudden headache and transforms back into his human form, as the Omnitrix was what kept him in his mutated form. Elated, Gwen kisses Kevin on the lips for the first time.
Vilgax regains consciousness and destroys the ship's console, sending it on a collision-course with Bellwood. Gwen and Kevin realize that the ship's fusion drive will destroy the city and everything else within 100 miles. Kevin and Max fight Vilgax in order to steer the ship away from Bellwood, while Ben approaches the chained Albedo, offering to free him in exchange for the Ultimatrix. When Albedo refuses, Ben orders the Ultimatrix to self-destruct as well; Albedo hastily surrenders the Ultimatrix, and Ben deactivates the self-destruct. Ben transforms into Swampfire and resumes the fight with Vilgax alongside Kevin, while Max and Gwen attempt to steer the ship away from Bellwood. Kevin is quickly defeated by Vilgax and Swampfire is overwhelmed. When Vilgax points out that Ben is losing, Ben transforms into Ultimate Swampfire, blasting the approaching Vilgax with an enormous burst of blue flames.
Meanwhile, Gwen and Max are unable to prevent the ship from crashing but manage to steer it away from the city and into the ocean. The ship crashes into the water and begins to sink, and Max, Gwen, and Kevin escape. Vilgax destroys the glass on the ship, flooding the ship's interior, and transforms into his true form, an enormous, squid-like monster. Vilgax attempts to eat Ultimate Swampfire, but Ben escapes by transforming into Jetray. Above water, Ben reunites with his teammates, and they embrace. As they watch the exploding remains of the ship, Ben surmises that Vilgax has survived worse, and vows to defeat him should he ever return.

==Continuity==
*Vilgax commands his Bioid army: hundreds of soldiers all with the power of the Omnitrix, finally fulfilling the dream that he confided to Ben in Secrets.
*Azmuth mentions that Ben disobeyed him and hacked the Omnitrix, which occurred in Vengeance of Vilgax: Part 1. Ben also mentions that he turned Kevin into a monster, as revealed in Vengeance of Vilgax: Part 2.
*Vilgax says activating the Omnitrix's Self-Destruct Mode would destroy the universe, calling back to Secret of the Omnitrix.
==Allusions==
*The voice command Ben uses to self-destruct the Omnitrix is identical to one used by James T. Kirk in the Star Trek original series episode Let That Be Your Last Battlefield, and again in Star Trek III: The Search for Spock.
==Errors==
*In the previous episode, Negative Ultimate Humungousaur was with Vilgax when he obtained the Omnitrix, but in this episode, he is not seen until he charges at the team before they teleport.
*Vilgax's Bioid army is arranged differently compared to the ending of the previous episode.
*Kevin is further away from Gwen compared to the ending of the previous episode.
*Max should not have been able to save the teleportation spell's page in Gwen's spellbook because he is not a magic user and does not know how to read magic.
*When Max hands over the spellbook to Gwen, Kevin has shaped his arm into a mallet but when Ultimate Humungousaur charges towards them, his hand is shown to be normal. Once Gwen casts the spell to teleport them, Kevin's hand is again shaped into a mallet.
*Before Vilgax transforms his Bioids into Humungousaur, the Omnitrix's dial pops up without Vilgax activating it.
*When Vilgax's Bioids transform into Humungousaur, they do not transform all at once but instead group by group.
*Ultimate Humungousaur reverts to Albedo without reverting to Humungousaur first.
*When Vilgax walks away from Albedo who is dogpiled by the Humungousaurs, four of the Humungousaurs don't have the Omnitrix symbols on them.
*The Rustbucket 2 does not have any holes from the damage it suffered in the previous episode.
*When Max stops the Rustbucket 2, there are no stripes on it.
*Despite it raining, neither Ben nor Gwen show any sign of getting wet when they are outside.
*When Ben walks past his jacket, there is a perspective error, where it looks much bigger than it should be.
*In Secret of the Omnitrix, transforming into an alien while the Omnitrix was in Self-Destruct Mode would cause the timer to accelerate. However, in this episode, that does not happen when Vilgax turns his Bioids into aliens.
*When Vilgax turns his Bioids into Humungousaur, the Bioids keep shouting Humungousaur's name, but when he turns his Bioids into Diamondhead, Lodestar, Spidermonkey and Swampfire, that doesn't happen.
*Before Vilgax transforms his Bioids into Diamondhead and Lodestar, their holograms face away from him. Furthermore, Diamondhead's hologram lacks the patterns on the stomach and legs.
*When the Bioids are transformed into Swampfire, they are farther than they originally were.
*The destroyed Omnitrix looks different between shots.
*When Kevin falls down after the Omnitrix is destroyed, there are no Bioids near where he and Gwen are, but when Ben runs towards him after hearing him scream, there are Bioids. This happens again when Vilgax smashes the ship's console.
*Before Kevin reverts from his mutation, his right arm is missing its shine.
*When Kevin reverts from his mutation, his head is on Gwen's lap, but when she stares at him along with Ben and Max, she seems to be at his side.
*When Kevin gets up after reverting from his mutation, there are four standing Bioids, but when he punches Vilgax, there is only one standing Bioid.
*When Kevin punches Vilgax, Albedo and the structure that he is chained to are missing.
*When Ben activates the Ultimatrix's self-destruct mode, he says "Omnitrix self-destruct" instead of "Ultimatrix self-destruct".
*When Ben puts on the Ultimatrix, the watch shrinks over the sleeve of his jacket. When he lifts up his arm, it is under his sleeve.
*Although Ben is wearing the Ultimatrix, the sound that it makes when he transforms into Swampfire is that of the Omnitrix.
*When Swampfire asks Kevin if he's got his back, Kevin is thinner than usual.
*Kevin is missing in one scene when Ultimate Swampfire and Vilgax are fighting.
*In one shot, Kevin's upper body features aren't drawn.
*Right before Vilgax's ship explodes, Kevin is to Gwen's left and Max is to her right. When they come out of the water, their positions are exchanged.
*Kevin's arm is doubled in one shot.
*Ben and Gwen seem to be shorter than usual compared to Kevin after Ben lands in the mana field.
* The Ultimatrix is not listed in the end credits.
