Dokurobei emerges as a shape-shifting figure across adaptations, each iteration altering physical form while preserving core traits. The 1977 version presents a stout, balding man with round glasses, a handlebar mustache, and a distinctive forehead skull. His outfit clashes in purples—shirt, skirt, gloves, and cape—paired with tan pants or bare legs. By 2008, the palette explodes: pink hair crowns his head, red lenses frame his eyes, and a green cape drapes over a blue shirt-skirt combo, though the skull emblem and mustache endure. The 2015 redesign stretches him into a gaunt silhouette, gray hair streaked with black, mustache elongating into a mask-like feature. A monocle replaces glasses, while red-and-black robes cascade over a skull-buckled belt.

Narratively, Dokurobei orbits deception. As the Dorombo Gang’s shadowy overseer in 1977, he spins lies about a golden map within the Dokuro Stone—a ruse masking his true goal: reassembling his extraterrestrial body fragments scattered during Earth’s fiery birth. Upon completion, he discards his pawns, fleeing to the Dokuro planet. The 2008 iteration weaponizes hope, fabricating a myth of wish-granting Skull Rings to siphon human ambition for power. When thwarted, he taunts the gang with promises of fifty more rings. By 2015, patience fractures; adopting the alias Lord Yatterman, he enslaves Earth through the Yatter Kingdom, retaliating against descendants of past adversaries.

Communication thrives on absurdity—orders barked via sentient hamburgers or crimson skulls flashing on screens. Failures trigger wrath, even when bred by his own misinformation. Speech crackles with “Beh” suffixes, echoing his skeletal motif, and insults like “Akapontan” pepper dialogues. A mercurial egotist, he fuels chaos not for conquest alone but for the thrill of puppeteering dupes, each scheme a mirror reflecting his manipulative essence.
