Reacoom (Recoome in the dub) is a large, muscular human-like alien with red hair. He is the most flamboyant member of the Ginyu Force, seen striking poses more often in battle than Captain Ginyu himself, and generally behaving in a deceptively goofy manner, however Reacoom is actually fairly intelligent, not to mention sadistic, as he greatly enjoys toying with his opponents and egging them on with taunts.
Of all the members of the Ginyu Force, Reacoom is the one who does the most damage to the Z Warriors. His exact power level is not known, but he appears to be as strong as Butta and Jheese, perhaps slightly more powerful. When Captain Ginyu has his men play Janken to divy up Gohan, Kuririn and Vegeta, Reacoom wins hands-down and gets to fight with Vegeta. Despite Vegeta striking first, throwing Reacoom into a mountain and blowing it up, and using a number of other crafty and underhanded tactics and techniques, Reacoom dominates the battle, apparently taking little damage from Vegeta's attacks except for his armor being destroyed and (later) his hair being burned off. It's likely that Reacoom would have killed Vegeta with his Eraser Gun attack had Gohan and Kuririn not stepped in, with Kuririn attacking Reacoom from behind while Gohan pulls the wounded Vegeta out of the path of Reacoom's attack.
Reacoom's only ill effects from Kuririn's attack are a few loose teeth, and after Butta and Jheese (bored by this point and anxious to leave) give him permission to fight the two Earthlings as well, he nearly kills Kuririn with a single kick to the head. Gohan he takes his time with, apparently admiring the boy's bravery and tenacity, but he ultimately brings the game to an end by breaking his neck with another kick. As he is about to finish off all three of them, Goku arrives, and after healing them using senzu beans, proceeds to defeat Reacoom by elbowing him in his stomach as he began warming up for his most powerful attack in a theatrically hammy fashion. The redheaded giant then keels over unconscious, much to the shock of everyone. Later, after Vegeta kills Butta, he also kills Reacoom, completely destroying his body with a huge ki blast (although in a later episode, a blooper results in Reacoom's perfectly intact corpse remaining on the battlefield).
He later travels to North Kaiō's planet with the other members of the Ginyu Force. There they find Tenshinhan, Chaozu and Yamcha. Reacoom gets to fight with Yamcha, who was holding back on him, because he saw what Reacoom did to Vegeta. After Yamcha realises that Reacoom is on a lower level than he is, Reacoom is quikly disposed off and sent into Hell along with the rest of the Ginyu Force. In the English dub, while in the prison of Hell, he offers an arm-wrestling challenge to anyone in their cell, but the only reply he gets is a unified "Shut Up!" from the rest of the Ginyu Force.
Reacoom is one of the longest lasting Ginyu Force members in terms of screentime, though chronologically he is defeated second and dies not long after. He is also the first member of the Ginyu Force to appear onscreen during the team's elaborate introductory routine to Freeza. Reacoom also makes a small appearance in Dragonball GT and it shows him flying out of hell with the other villains.
Reacoom's Japanese name, Rikuumu, is the Japanese word for cream kurīmu (cream) rearranged. Viz went with the spelling of Reacoom in the DBZ manga to reflect this pun. He returns in the movie Fusion Reborn along with Butta, Jheese and Gurd.
