Jekyll & Hyde: Changes into the hyper, fun loving Funstro after pulling out one of his fangs. Then when both of them are removed, he grows a much larger, intimidating-looking pair and becomes the violent, overly aggressive Fightstro.
Idiot Hero: Has bigger muscles than brain cells unfortunately.
The Leader: Prides himself as being the most dominant of the five Disgustoids.
Real Men Hate Affection: Being a testosterone-riddled fratboy, stuff like romance and soppiness are a big turn-off for him, especially in the episode where he tries breaking up the fort's relationship with a volcano.
Politically Incorrect Hero: He's also implied to have misogynist tendencies, as seen in "The 6th Disgustoid" where he was horrified by the fact that their new lodger Bromandor is a girl, which didn't seem to bother the other Disgustoids.
