*Spoilers*
Death (Final Destination Series and others) - Death is not evil it is just doing its job when peoples time is up.
Dr. Lisa Cuddy (House) - have no clue how she is a villain
Mao - Can't think of anything evil he did
Sagat- from what I knew of him he was part of the same organization as Bison and working for him. with this other information he does not sound so evil. More of a rival to Ryu.
Seto Kaiba - His goal became to beat Yugi. not evil or villainous
Spike Joins the scooby crew. He fights evil and made the choice to regain his soul.
Angelus - according to Buffy lore once turned into a vampire you die and a demon inhabitats your body. now gypsy's cursed Angelus to regain his soul and he became Angel with a part of the human coming back and it had memories. I personally think Angelus is the Demon and Angel is the human part that can control it/its strength.
Boba Fett: In the movies worked for Jabba the hutt to bring in Han. Did not seem evil but was kinda a villain
Ghaleon Evil baddie
