Ben 10: Ultimate Alien

After Vilgax is defeated, he is seen in his outfit from Alien Force. However, he lost it in the ocean after transforming in "The Final Battle Part Two".

The cosmic ray that Way Big shoots was first seen in the video game Ben 10 Ultimate Alien: Cosmic Destruction.

Ultimate Kevin makes a return appearance in this episode, even though it was all in Albedo's dream.

This is the first time we see Ben's transformation into AmpFibian.

Even though Albedo changed from being Gwen, Kevin's body is still there as well with Albedo changing into Fasttrack.

Kevin says that Albedo tripped on his smoothie, but the correct word to say is 'slip'.

At the end of the episode, the evolve ray affected Sheriff who was watching TV. After being evolved, he turned off the television and his intelligence was increased allowing him to complete his crossword puzzle.

It is revealed that Ben and Kevin train with Ben's new aliens to find out their powers and abilities.

Jury Rigg always says what he is doing repeatedly, when breaking something he says "break" and when fixing something he says "fix" over and over again.

Jury Rigg is one of Ben's alien forms who is not in the lineup of aliens in the Ultimate Alien intro, the others being Fasttrack, Eatle, Ultimate Wildmutt, Clockwork, Shocksquatch, ChamAlien and Ultimate Way Big; although this is due to their existence not being known until just recently.

What they refer as "dragons" are really "pteranodons" as shown by the crossword puzzle near the end that refers to "Pterano", a pteranodon character on the "Land Before Time" movie series.

Gwen refers to the group meeting a "dragon", from the Ben 10: Alien Force episode "Be-Knighted."

Captain Nemesis/Overlord's real name is revealed to be Carl Nesmith.

We find out that Gwen has 15 security spells protecting her house.

It is revealed that time in Legerdomain moves faster than on Earth; Darkstar takes two days to recuperate, in which only minutes pass on Earth.

Gwen puts a book back on the shelf in Hex's library, this must be the same book she took back "Time Heals".

This episode might have took place after "Absolute Power" seeing how Gwen talks about Aggregor and that she promise to help Charmcaster.

Kevin mentions previous alliances the team has had with villains, such as Sir Conner (from the Ben 10: Alien Force episode "Be-Knighted"), Darkstar (from the AF episodes "War of the Worlds") and Vilgax (from "Ghost Town"). An unspecified alliance with Dr. Animo is also mentioned.

Charmcaster's secret true name is revealed to be "Hope."

It is revealed that if Echo Echo is holding something when he duplicates himself, that object will be duplicated also.
