Groribas

Bulk and muscle define his hulking frame, which carries streaks of green over the shoulders and midsection. His head bears no eyes at all, and where hands should be sit toothy maws shaped like crab pincers. A spiked collar rings his neck, and a lengthy green tail trails behind him, tipped with a fourth head.

He carries himself with immense self-assurance about his fighting ability. There is a comical streak to him as well: en route to Saitama he cannot even settle on which of his attacks to use. Beneath that detached air, he takes pleasure in drawing out his victims' deaths slowly.

His Dragon-level rating marks him as tremendously strong, and Geryuganshoop flatly named him the group's best warrior despite how quickly Saitama disposed of him. As a Dragon-tier being he is presumed to wield formidable power, said to have slain most of his foes before ever showing his full range of moves.

He claimed his Acid Breath could dissolve anything, though the ability never got a chance to appear on account of how fast he died. By his own account he held twenty techniques and, judging by their names, favored close-range brawling. Among the moves he mentions are Double Bite, a two-armed assault, plus the unrevealed Purgatory Thorn Grip, Sky Strangle Sunder, and Screw Tail Thrust.

When he and Geryuganshoop detect Saitama aboard the ship, Groribas volunteers to handle the intruder, mulling over which special attacks to unleash as he approaches. He then makes a brief, hopeless attempt to keep Saitama from wrecking the vessel further; while bragging about his corrosive breath and squaring up, he is decapitated by a single, almost bored strike. Word of note: creator Murata stated that even Melzargard, Groribas, and Geryuganshoop working in concert with preparation would stand almost no chance against Orochi.
