Ultimate Humungousaur

Ultimate Humungousaur is a playable Exosuit of the Atlas Brigade on Project Exonaut. His Weapon Mod, similar to Finn, increases the Tridex's Shots to five instead of just three. Ultimate Humongosaur is available for purchase at level 10 for 750 coins. Those who prefer to get up close and personal would find this suit best.

In The Show
Ultimate Humungosaur is a form of Ben, a child who finds an alien device called the Omnitrix which allows him to transform into any of ten alien forms (Although later on, he gains more). However, in a fight with his arch nemesis, Vilgax, the Omnitrix is destroyed and he gains the Ultimatrix, which can transform him into the Ultimate Form of an alien (Meaning where evolution would make the alien undergo a million years of harsh conditions). One of his transformations, Humungosaur turned green, bulkier and gained mass when transformed into an Ultimate form, alongside the ability to fire unstable bone fragments as Gatling Missiles.
