Satan as he appears in his various versions

 

Name: Satan, Ryo Asuka (the human disguise that Satan undertook)
Origin: Devilman
Gender: Hermaphrodite, male as Ryo Asuka
Classification: Demon
Age: Unknown
Powers and Abilities: Super strength, speed, durability, endurance, telepathy, shapeshifting, immortality, instantaneous teleportation, the ability to merge with a living being or an inanimate object to gain its characteristics, the ability to create a country+ wide sphere of light that turns anything in it's vicinity into salt, flight, reality warping, can survive in space, possible space-time manipulation (since he is much superior to characters who have these type of abilities), can exist in time loops (God trapped him as punishment in an endless time loop, by having to relive the same events over and over, even if they are slightly changed/altered in the various series he appeared), can revive/resurrect others, astral like projection, can melt/explode body parts of his opponent, etc
Weaknesses: In order to merge with a human there are requirements, the human must not have reason (a spirit to live) as demons hate this but act on instinct alone instead, if the human has a strong will they will get the demon's power and have full control and unsuccessful fusion will result in suicide
