Deep

Deep is the third episode of the second season of Ben 10: Ultimate Alien, and the thirteenth episode overall.
==Synopsis==
Ben, Kevin, and Gwen journey to the center of an all-water planet in an attempt to finally capture Aggregor.
==Plot==
Underwater on Piscciss, a Magister Plumber named Pyke is searching for something. He finds a swimming object, which happens to be Ultimate Aggregor, who seems to defeat Magister Pyke.
Meanwhile on Earth, Ben is surrounded by fans and transforms into Goop in order to escape but fails, requiring Gwen and Kevin to save him. Ben receives a message from Pyke about Ultimate Aggregor on his Ultimatrix, and Ben's team goes to planet Piscciss in the Rustbucket 3 to search for Pyke, but they are attacked by a squid-like monster. They use the electrical gauntlets in their Plumber suits (specially modified by Kevin) to defeat the monster, but in the battle, Kevin's helmet cracks.
With Kevin drowning, Gwen blasts him against the jet's side, causing him to absorb the jet's coating, saving him from being crushed by the water pressure, but he still can't breathe. A nearby fish appears and is able to convert itself into a helmet for him so he can breathe. Pyke shows up and they go with him to find Ultimate Aggregor. Ben's helmet cracks when they battle some sea creatures, and he transforms Humungousaur (who cannot breathe underwater). He scares them off and transforms into Ampfibian instead.
They pass the guards once they explain their Plumber business, and go to the core of the planet, where it looks like Ultimate Aggregor is attacking. The core has air in it, allowing them to operate without their suits, while Pyke uses a water helmet to breathe. A tremor occurs, and Pyke is crushed by a rock. While Gwen stays to help him, Ben and Kevin go on, but find Ultimate Aggregor grabbing the planet's core piece that keeps it together.
It turns out the anti-gravity multiplier that holds Piscciss together is the second piece of the Map of Infinity, which Professor Paradox disguised so no one would suspect it. Ultimate Aggregor leaves and Ben transforms into Big Chill and chases him, leaving Gwen, Kevin, and Pyke with the core guards. Big Chill evolves into Ultimate Big Chill when the guards keep distracting him, and Pyke accuses Ben and his friends as the culprits for stealing the core piece. Ultimate Aggregor takes advantage and escapes Piscciss in all of the commotion. 
Ultimate Big Chill transforms into Goop again and tries to stop Piscciss from shattering into pieces by using his Anti-Gravity Projector as a substitute, but it also sucks in Goop. Soon, the water turns green and Piscciss pulls itself back together, with Goop transforming back to Ben and being saved before he drowns. 
Pyke thanks them for their help and Kevin wards off the fish that was used as his breathing helmet, much to his sadness, while Gwen consoles him.

*﻿When Pyke got his water helmet, Kevin was shifting between his normal form and his metal form.

*When Pyke is dehydrated inside the core, the Piscciss Volann guards have grey anglers.
*When Big Chill is chasing Aggregor, two Piscciss Volanns start to chase him, for a moment it can be seen that the one on the right has Magister Pyke's design.
*The whole time Goop is pulling the planet together, Pyke does not have his helmet on and yet shows no discomfort.
