Powers and Abilities: Super strengthspeed and durability, knowledge in the martial arts
Weaknesses: Needs oxygen to breathe, has no counter for energy attacks, cannot fly
Destructive Capacity: Wall level+ (probably higher)
Range: Human melee range; several dozen meters with his pistol
Speed: Above peak human

Striking Strength: Around Class KJ
Stamina: Above peak human (was able to stand after being heavily damaged)
Standard equipment: Has various weapons and poisons in a duffel bag, but he wouldn't use them if there were witnesses around
Intelligence: Master martial artist (of the sort that doesn't let you shoot energy beams that can destroy planets). Master of combat tactics. Figured out that the Z-senshi's powers were real when most of the general populace still thought they were tricks. His buffoonish personality makes him seem less intelligent than he is.
Notable Attacks/Techniques:

- Dynamite Kick: Just a flashy flying kick.

- Megaton Punch: Just a punch with a fancy name.

Notable OBD Losses:

Other: Mr. Satan's feats are extremely difficult to quantify due to many of them being comedic moments, and the OP should explain what feats are being counted. Notable for being the only character in Dragon Ball to not die at least once, along with the Supreme Kai.
