Shingo Riki

Shingo Riki is a 14-year-old middle school student who becomes Humungousaur/Ultimate Humungousaur with his light brown Ultimatrix.

Powers & Abilities

As a basic form, Humungousaur possesses incredible strength, being able to lift and throw a To'kustar and at base size, and throw objects (heavy or light) up to a high altitude, even into near-earth orbit.

Humungousaur possesses a thick, armored hide, which has proven to be durable enough to withstand blaster fire and heavy impacts.

Humungousaur has the power to increase or decrease his own body size and mass. He can grow bigger up to about 60 feet at will, increasing his natural strength as he grows. He can also shrink down to about 10 feet.

When Humungousaur grows, his dinosaur features become more pronounced, growing Stegosauride features such as plates on his back, a crest on his forehead, and spikes on his tail. The plates on his shoulders and arms also separate and grow, giving him a more ferocious look. These features give him an extra edge in battle both defensively and offensively. Humungousaur can also generate his Stegosauride features without changing size.

Humungousaur is durable enough to survive in the vacuum of space for a few minutes and pass through dangerous force fields.

Humungousaur is capable of jumping extremely high despite his size and weight.

Humungousaur can run on all fours in a similar fashion to a bull or a rhinoceros.

Humungousaur is quite agile for his size.

Humungousaur has powerful jaws.

Humungousaur's immense size and weight make him very useful for moving against strong suction forces and powerful winds.

Humungousaur has a powerful roar.

Humungousaur is strong enough to create shock waves by clapping his hands together.

Humungousaur (2)

As an ultimate form, Ultimate Humungousaur is exponentially stronger than Humungousaur, even when at full size. While Humungousaur is strong enough to lift and throw a To'kustar even at his base height, Ultimate Humungousaur is strong enough to both accomplish this feat in record timing and make a giant crater in the ground by punching it.

Ultimate Humungousaur has very durable armor plating throughout his body, giving him enhanced durability combined with his thick skin.

Ultimate Humungousaur can transform his hands into bio-gatling guns that shoot kinetically unstable bone fragments as missiles, which deal major damage.

Ultimate Humungousaur's tail has a mace-like structure at the tip, which can be used as a flail.

Like Humungousaur, Ultimate Humungosaur can survive in the vacuum of space for a short time and can create shock waves by clapping his hands.

UHUA (2)


As a basic form, Humungousaur's strength has a clear limit, as with such cases with moving and lifting beings or objects as heavy as his species' natural predator, the Tyrannopede, whose sheer weight proved a challenge for Humungousaur to manage, and when he was encased in Tyrannopede's cocoon, he was unable to escape.

Humungousaur is very slow and combined with his naturally large physique, it makes him a very easy target for enemy attacks. Even his base size makes it impossible for him to fit into small spaces.

Humungousaur can be discomforted by an Aerophibian's neuroshock blasts.

Humungousaur is weak against electricity.

Humungousaur is more of a land-based alien, meaning he cannot breathe underwater.

Humungousaur can be harmed by a Methanosian's fire attacks. Similarly, he can be harmed by a Pyronite's fire attacks even while he has his Stegosauride armor.

Despite his enhanced durability, Humungousaur's feet can be badly hurt by a strong enough blow, similar to those of a human.

As an ultimate form, Ultimate Humungousaur lacks his devolved counterpart's ability to change his size.

Ultimate Humungousaur's missiles can be absorbed by Conductoids.

Like Humungousaur, Ultimate Humungousaur is vulnerable to electricity, such as that generated by a Conductoid.

Despite his enhanced strength, Ultimate Humungousaur can still get muscle cramps, meaning his strength has a limit.
