Eleph

Bulk defines him. Eleph is a heavy, obese Nomu built along the lines of a humanoid elephant, and three glowing lines trace his trunk, the first running from his exposed brain to the tip. Two more sit beneath a pair of angular eyes, each carrying three glowing diamonds strung in a line. Tiny feral pupils eventually surface in those eyes, most likely red like Hood's, and his spine pushes out prominent vertebrae in the same way. Once his Arm Bulk Up Quirk kicks in, arms already thick with muscle swell further and turn ropey with veins.

Almost nothing is established about him as an individual. Like the rest of his batch, he wakes up hungry for a fight and wastes no time looking for one.

Kyudai picked him deliberately, choosing a subject he could shape into a Nomu devoted to raw strength and little else. When the heroes raid Jaku Hospital, Kyudai moves to escape with Tomura Shigaraki using Johnny's Warping Quirk, but Mirko crashes into the lab first, killing Johnny by accident and stranding the doctor. Cornered, Kyudai wakes five High-End Nomu, Eleph included, to drive Mirko back while he tends to Tomura. Under Woman's improvised command, Eleph piles in with the rest to hold the hero off. Pro Hero reinforcements eventually swamp him, and when Tomura finally awakens, his Decay wipes out Eleph along with every other High-End.

His power is respectable by Nomu standards. Two of his Quirks work on his musculature, and a single grab tore a fistful of hair straight off Mirko; despite the size, he tracked and kept pace with the No. 5 Hero well enough to land that hold. Super Regeneration, standard to all High-Ends, let him heal from whatever he took. His unnamed Elephant Quirk supplies the silhouette, the heavy muscle and the trunk, adding a third limb for grappling and probably sharpening his sense of smell, while the unnamed Arm Bulk Up Quirk swells his arms enormously and drives his grip to that hair-tearing extreme.
