He now has tattoos and has a belt with bones on it.
Powers and Abilities
Humungousaur possesses incredible strength. According to Eugene, Humungousaur is strong enough to lift Way Big.He is able to throw an object to up to a high altitude, even into near-earth orbit.
He possesses a thick, armored hide, which has proven to be durable enough to withstand blaster fire and heavy impacts.
In Vilgax Attacks and Cosmic Destruction, Humungousaur can do a shoulder charge and make shockwaves by slamming the ground.
Humungousaur has the power to increase his own body size and mass. He can grow up to 60 feet. His strength increases as he grows.
Humungousaur can generate his Stegosauride features (plates and spikes on spine) without changing size.
In the video game Ben 10: Alien Force, Humungousaur was shown to be immune to freezing.
Humungousaur is durable enough to survive in space for a few minutes.
Humungousaur's tail is powerful enough to knock away Malware's third form easily, as shown in Showdown: Part 2.
In Primus, Humungousaur charged and rammed Vilgax while running on all fours, in a similar fashion to a bull or rhinoceros.
Humungousaur is quite agile for his size, as he could somersault onto one of the Forever Knights' battle horses in Eye of the Beholder, perform a slide tackle in Special Delivery and be able to evade attacks while jumping in Showdown: Part 2.
Humungousaur has a powerful roar, which he used to scare away some reporters as seen in Fame.
Humungousaur's strength has a clear limit, as with such cases with moving and lifting beings or objects as heavy as Tyrannopede, whose sheer weight proved a challenge for Humungousaur to manage. Humungousaur is also very slow and combined with his naturally large physique makes him a very easy target for enemy attacks. Even his base size makes it impossible for him to fit into small spaces. However, his greatest weakness is his extreme vulnerable to electricity.
