|Behind the Scenes|
|Universe||Ben 10 Universe|
An evolved Vaxasaurian somewhat resembles their precursor but with green skin, grey horns on their head, arms, chest, and back, an armored shell on their back, an ankylosaurid-based helmet-like extension on their skulls, sharper claws, dark blue chest plates, and a mace-like structure at the ends of their tails.
Sometimes, an evolved Vaxasaurian can instead have pale light brown skin, yellow horns, armored shells on their back and shoulders, an ceratopsidae-based helmet-like extension, and exposed metallic plating and veins.
Generally, evolved Vaxasaurians become bigger, bulkier, heavier and stronger, being able to take on an army of regular Vaxasaurians. They stand 20 ft. tall. They can grow up to 120 ft. It is unknown at present whether their dinosaur features grow more pronounced with size, as it has not been seen to grow.
They additionally gain the ability to change their hands and fingers into a missile launcher/barrel cannon-like weapon that fires bone fragments in the shape of bullets.
