Humarise's Rampage Villain spent nearly all of his screen time drugged out of his mind on Trigger, which is why nobody knows what the man actually believes. What is documented is that he almost drowned Shoto Todoroki in an underground river and shrugged off fire that would have finished anyone else.
Trigger turns Leviathan into a bleached slab of muscle standing over eight feet, black markings running across his face and his forearms, with one line of brown spikes tracking down his spine. The head sits small on that frame, carrying eyes that are tiny and orange-yellow above a broad rack of teeth. Red spirals coil off every finger and toe, and matching tube-like growths climb from his back to his skull. Torn black trousers and a brown belt are all he bothers wearing.
The brief glimpses of him off the drug show a man still heavily built but nowhere near that scale, with fair skin, smaller spirals on his head, and appendages that are white rather than red.
What Leviathan personally believes has never surfaced, because he is almost always dosed and Trigger leaves nothing behind but a violent rampage. The one thing that can be said with confidence is that he carries out Flect Turn's plan with the same devotion as the rest of Humarise.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Overall Abilities: The moniker Rampage Villain was earned. His grip on Helical Scythe is solid, and layered over Trigger it let him overwhelm one of U.A. High School's strongest students and come close to killing him, since Shoto Todoroki's arsenal barely registered. Strength matches the frame: he shatters solid concrete, stomps out a wide section of flooring in the Humarise hideout, hauls big chunks of ice around, and tears through ice walls with his tendrils. Durability is the worse news. He bathed in Shoto's flames, absorbed repeated high-output blasts, and took tons of falling ice and rubble plus a long drop into a canal without slowing down.
Helical Scythe: The red growths riding his fingers and his skull lengthen and obey him, functioning as whips at range and boring through obstacles like drills. Their reach is wide, and because he has only ever been observed using the Quirk while dosed, its true ceiling is unknown. Beyond direct strikes, the tendrils manipulate whatever is around him: he steered a column of water to snare Shoto and hold him under, and later seized the fire of an explosion to build a giant burning replica of himself that swallowed the boy whole. He takes Trigger before engaging, which amplifies the Quirk and switches off his sense of pain.
Flect Turn sent him and the Serpenters after the Endeavor Agency interns arriving on Rody Soul's chartered plane. With Katsuki Bakugo tied up by the Serpenter twins and Izuku Midoriya pushing deeper toward the bombs, Leviathan crashed into Shoto. Flame failed to stop the charge, an ice-blocked door failed to hold him, and he dragged both of them down to an underground river, regrowing tendrils faster than Shoto could freeze them off while pinning him beneath the surface. Shoto escaped by riding the current toward a waterfall, kept the tendrils frozen this time until the fall itself broke him loose, then froze the villain, the appendages, and the entire waterfall at maximum output. Leviathan freed his head anyway and turned the resulting Flashfreeze Heatwave explosion into his fiery construct, at which point Shoto concentrated everything into Flashfire Fist: Jet Kindling and burned him out from the inside. Both fell unconscious into the river below. Once the Trigger Bombs were defused and Flect Turn went down, Leviathan was arrested along with the surviving membership.
Leviathan is a member of Humarise known as the Rampage Villain, first appearing in the movie My Hero Academia: World Heroes' Mission. He nearly drowned Shoto Todoroki in an underground river while dosed on Trigger and carrying out Flect Turn's plan.
Leviathan is from My Hero Academia, specifically the movie My Hero Academia: World Heroes' Mission, where he serves as one of Humarise's enforcers. He is not connected to any other anime series.
Leviathan's Quirk is Helical Scythe, which lets the red growths on his fingers and skull lengthen into whip like drills that he can also use to manipulate objects around him, such as steering water or fire. He has only ever been shown using it while dosed on Trigger.
Beyond his Helical Scythe Quirk, Leviathan under Trigger has enormous physical strength, capable of shattering concrete and hauling large chunks of ice, along with durability strong enough to shrug off Shoto Todoroki's flames and repeated explosive blasts. Trigger also removes his sense of pain while amplifying his abilities.
Leviathan was defeated by Shoto Todoroki, who froze him along with an entire waterfall before burning him out from the inside with Flashfire Fist: Jet Kindling. Both fighters were knocked unconscious into the river, and Leviathan was arrested once Flect Turn's plan collapsed.
