Clawful is a member of the Evil Warriors, he appears to be a hybrid between a man and a crab or lobster, with large, sharp claws that can crush the life out of his opponents. He has fin like spikes down the back of his head which makes his head look almost reptile (or even dragon) like.
Introduced in the episode "Dree Elle's Return", Clawful receives a strong introduction as lead villain of the episode. Having stolen an artifact called the Horn of Evil from Orko's homeworld of Trolla, Clawful is portrayed as a strong, harsh commander to the bumbling Trap-Jaw who assists him throughout the episode. He makes his second appearance a few episodes later in "Castle of Heroes" in which Skeletor describes him as his "right-hand man" and he is portrayed as such throughout the episode, as a loyal sidekick to Skeletor, whom Skeletor seems to respect more than most of his other warriors. Although his introduction seems to indicate he is a rung above the other villains, this is not expanded upon throughout his later appearances, most of which portray him as just another of Skeletor's henchmen, albeit more intelligent and slightly more responsible than most others.
His most prominent episode of the show's second season is "Things That Go Bump in the Night", which indicates that Skeletor's apparent respect for him, as demonstrated in "Castle of Heroes", has waned, as Skeletor is shown to be aggressive and distrustful towards Clawful, who in this episode vows that he will someday overthrow Skeletor as leader of the Evil Warriors. Clawful seems to possess more confidence than Skeletor's other minions in that out of all of the Evil Warriors who make this statement for themselves throughout the series, Clawful is the only one bold enough to say it to Skeletor's face, and he is also seen to sarcastically laugh off Skeletor's abuse with a confidence few other evil warriors ever exhibit.
