He 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. In most media, his right claw is extra large and thus achieves an extra-deadly grip.
Clawful was introduced into the Masters of the Universe toy line in 1984. However, he makes his debut on the accompanying cartoon series by Filmation in 1983, late into the show's first season, earlier than most other characters from his wave of toys. His appearance on the cartoon is significantly different from the appearance of his action figure. He is given fins, which make him resemble a sea creature more closely, and unlike the action figure, both his claws are the same size, the reason for this being to make his character symmetrical so animation cells could be flipped over without his large claw constantly switching sides.
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 significant 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.
2002 seriesClawful is re-used in the 2002 relaunch of the Masters of the Universe cartoon series. Despite being one of the first characters designed by the Four Horsemen for the new toyline, the line was canceled before his figure could be released. In 2004, a mini statue of the character was produced by NECA.
Clawful's portrayal in the modern incarnation is radically different from his 1980s counterpart. Rather than being one of Skeletor's more intelligent and responsible villains, Clawful is presented as being the stupidest and most bumbling of them all, used purely for comedy value without the faintest hint of intelligence. Although he appears frequently throughout the series, his roles are generally very minimal, only serving to contribute the occasional comical moment with his dim-witted statements and bunglings of schemes.
The only episode to give him a spotlight role is "The Island", in which we are introduced to his race, a race of crab-like creatures who populate a small island. Clawful's cousin plays a larger role than Clawful in this episode, and also seems significantly more intelligent, to the point the audience could wonder why it was Clawful whom Skeletor had hired and not his cousin. Clawful is shown to be so dim-witted that he does not even recognize the language of his own race: communication via a snapping of the claws.
One interesting factor about his character is that Evil-Lyn, despite her general resentment of the other Evil Warriors, actually seems to like him, seeming rather sympathetic towards Clawful's lack of intelligence and his almost childlike personality. The modern series' radical change of Clawful's personality proved extremely controversial among fans, who felt it undermined the effectiveness of a character who had shown so much promise in his original incarnation.
- Clawful appears in only two of the minicomics that came with the toys: "The Clash of Arms" and "Mantenna and the Menace of the Evil Horde!".
- The writers of the 2002 series had conceived an idea for an episode in which Clawful gained high intelligence, but the show was canceled before such an episode could be written.
