The Ultimatrix is Azmuth's greatest invention.
Azmuth is the smartest being in three galaxies, arguably five galaxies.
The Omnitrix wasn't intended for Ben, it was intended for Max. But Ben's DNA Signature was close enough to Max's that it allowed him to put it on.
Max is the Greatest Plumber in the Milky Way Galaxy.
When Ben is watching Sumo Slammers with Kevin, the Omnitrix has somehow disappeared from Ben's wrist.
Ben mentions Sumo Slammers sequel, "Hero Generation" which takes place 5 years after the original. Hero Generation was the working title of this series prior to Alien Force which takes place 5 years after the original. Ben also mentions the far fetched storyline of Kenko joining up with Ishyama for the sequel. This is of course, a reference to Kevin, a villain in the original series, becoming an ally in Alien Force.
Humungousaur: I've beaten tougher guys than you.
Ultimate Humungousaur: Really? When?
Humungousaur: For starters, how about now?
Albedo: Greetings, Ben Tennyson. Since your grandfather managed to escape me, you must already know that I'm after you. But did you know that I have your friends?
Ben: Albedo, let them go, or...
Grandpa Max: Easy, Ben. He wants you angry.
Ben: Then today's his lucky day!
Ben: (about Kraab) You guys saved him?
Kevin: In my defence, (Gwen) made me.
Gwen: You should be more careful.
Ben: What for? I always win anyway.
Gwen: Nice attitude.
Ben: Hey, my overconfidence is one of my most endearing qualities.
Gwen: No, it really isn't.
(Albedo transforms into Ultimate Humungasaur)
Albedo: Meet.... Ultimate Humungasaur!
Humungasaur: I've beaten much bigger guys that you before!
Albedo: Really, when?
Humungasaur: For starters.... how about now!
(Ben punches Albedo)
It is revealed in this episode that Ben has the ability to remove the Omnitrix from his wrist at any given time via voice command.
Vanessa Marshall does not reprise her role of Myaxx from "Secret of the Omnitrix." Instead, Vyvan Pham voices her here. Jeff Bennett voices Kraab who was previously voiced in the first series by Billy West. Yuri Lowenthal briefly voices Ishyama who was previously voiced in the first series by Keone Young. Paul Eiding briefly voices Kenko the Shapeshifter who was previously voiced in the first series by Clancy Brown.
This marks the first appearance of Ultimate Humongousaur. However, Albedo is the first to use this form rather than Ben.
Humungousaur has a new transformation sequence.
Albedo's alien forms all have red eyes and Omnitrix symbols. Also, his transformation sequences are all tinged red.
Myaxx, last seen in Secret of the Omnitrix, returns, apparently back as Azmuth's assistant. Her appearance has changed; she is slimmer, with more chin tentacles, and a new outfit.
Alien Form(s) Used by Albedo:
6) Ultimate Humungousar
Alien Form(s) Used by Ben:
1) Big Chill
The ability to evolve aliens to their ultimate form is similar to Pokémon, where a Pokémon would start off at their base form and then as soon as they reach a certain level they would evolve.
