The Secret of Chromastone

The Secret of Chromastone is the sixteenth episode of the second season of Ben 10: Alien Force, and the forty-second episode overall.
==Synopsis==
Ben meets up with Tetrax but is caught off guard when Tetrax demands that he give him Chromastone. Before Ben has chance to explain, Tetrax attacks.
==Plot==
The episode begins with Ben having a cold and Kevin driving him to Mr. Smoothy. Kevin purchases a smoothie for Ben in order to make his cold remedy go down better. Ben drinks it and the taste of the smoothie is terrible. Then, a ship lands next to the car and the team gets out. Tetrax, Ben's old ally and friend when he was 10, exits from the ship. Tetrax grabs him, demanding that he give him Chromastone.
Tetrax throws Ben on the ground, and he asks him what he wants with Chromastone. Tetrax then tries to transform Ben into Chromastone, but Ben transforms into Diamondhead instead, angering Tetrax. However, Tetrax senses Chromastone's essence within Diamondhead, but before he can explain, Kevin and Gwen approach Tetrax for attacking and are easily defeated. Tetrax is left with no other choice and uses a sonic device to shatter Diamondhead and reveals a Crystalsapien inside. Tetrax gives the Crystalsapien a back-up crystal that alters the colors of his crystals from magenta to red. As he flies off into space, Gwen ties up Tetrax with mana, demanding an explanation after they put Diamondhead back together. Kevin assembles all of the parts of Diamondhead he can find, and transforms him back into Ben. Ben instructs Gwen to let Tetrax go. Afterwards, Tetrax apologizes for what he did and explains that he discovered a way to resurrect his home planet, Petropia, through giving Chromastone the crystal that Vilgax used to destroy it when the planet's suns align. Chromastone would then line up with the stone and the crystal would bring back Petropia and its residents. Tetrax stole the crystal and gave it to the Crystalsapien, who was created to be Petropia's guardian. Vilgax arrives and demands the crystal.
The four run from Vilgax and Ben attempts to transform into Way Big, but he transforms into Humungousaur instead and attacks Vilgax. Humungousaur then transforms into Jetray as the team retreats. While in outer space, the Crystalsapien arrives at Petropia's ruins and lines up with the suns. The planet's pieces start to come together. As Jetray and Vilgax fight, Jetray turns back and Ben begins to fall. Luckily, Gwen catches Ben with a mana slide and Kevin, having an idea, runs off and gets into his car. Vilgax attacks the rest of the team and demands the crystal from Tetrax. Kevin picks them up in the car and creates a smokescreen. Vilgax shoots into it and goes up to the car, but the team is gone. They escape into a building through the sewers, but Ben sneezes and Vilgax hears it with his super hearing. Vilgax arrives and demands the crystal. Ben transforms into Echo Echo and creates duplicates of himself. The Echo Echos sneeze a sonic sneeze, which knocks Vilgax away, and transforms back into Ben. Vilgax attacks the team and grabs Tetrax. Tetrax says that Vilgax will never find the crystal, but Kevin mentions that the Crystalsapien has it and Vilgax flies away. The team gets into Tetrax's ship and flies to Petropia after Vilgax. The Crystalsapien has rebuilt the planet and is about to resurrect the people when Vilgax arrives and attacks him.
The Crystalsapien begs for mercy, but Vilgax tears the crystal off of him and discovers that it is drained of power, Vilgax then flies away and leaves him to die. The team arrives and finds the Crystalsapien near-dead, but in a last-ditch effort, he grows another crystal and gives it to Ben before he dies. Ben has no idea on what to do with the crystal, but then transforms into Diamondhead, believing that Diamondhead would. Diamondhead climbs to the top of the planet's tallest mountain and hold the crystal up to the stars. The Petrosapiens are resurrected, and Diamondhead returns to the team and transforms back into Ben. The Crystalsapien is also revived, revealing that his name is Sugilite, and Chromastone is still in his Omnitrix. Ben gives him the crystal and he reattaches it. The Petrosapiens cheer for Ben. Tetrax then brings the trio back to Earth. Ben thanks Tetrax for the ride home. Tetrax tells the trio that it was the least he could do. Gwen says that she, Kevin and Ben really don't want to hold him back as he must be anxious to get back to his friends. Tetrax replies that he is, but first; he has a score to settle with Vilgax. Ben wonders if Tetrax doing this is really such a great idea, as Vilgax is pretty much invulnerable. Tetrax just replies with a simple "Maybe.... Maybe not". Speaking of Vilgax, he has unfortunately caught Ben's cold, and the episode ends with Psyphon giving Vilgax a tissue to cure his cold.

==Cast==
==Allusions==
*When Kevin says "Don't worry, in space nobody can hear you sneeze", it is a reference to the famous 1979 film Alien tagline: "In space, no one can hear you scream".
==Errors==
*When Tetrax scrolls through Ben's aliens before transforming him into Diamondhead, their holograms face away from him. Furthermore, Brainstorm's hologram lacks the brace.

*When Sugilite says "Not Ben", his mouth doesn't move.
*Kevin's body is reciprocated twice.
*When Diamondhead wipes his finger on his face, his arm is drawn incorrectly.
*Although the Omnitrix would cause Ben to carry any damage sustained while transformed, he is unscathed despite Diamondhead being shattered by Tetrax. 
*The Resolute has its daytime colors instead of its nighttime colors in several shots.
*Echo Echo's hologram has an elongated neck.
*When Ben is about to select Way Big before mistransforming into Humungousaur, an alien's hologram pops up but vanishes quickly. The alien in question isn't clearly visible.

*At one point while Diamondhead is carrying the Petropia Back-up Crystal, it is pink instead of red.
*All of the Petrosapiens in the crowd appear to be adult males and have Chromastone's body texture.
*In one shot, Sugilite's eye is on his forehead.
*When Sugilite talks to Ben at the end, he says "I am in your debt, as are all Crystalsapiens", instead of Petrosapiens.

*Many changes were made to the scene where Tetrax witnesses the destruction of Petropia.
*Humungousaur turns into Jetray without touching the Omnitrix symbol, similar to the Master Control.
*Tetrax's flashback, where he gives Vilgax the Petropia Back-up Crystal from Secret of the Omnitrix, was recreated in this episode.

*When Diamondhead revives the Petrosapiens, no female or child Petrosapiens are seen.
*The episode's title is listed as The Secret of Chromastone! on Amazon Prime Video.
