Here I'll attempt to make a comprehensive list of all the basic Werewolf and Mafia roles we use. Those that are labeled ADV are advanced roles and not allowed in Mafia games without permission from a permamod. By default, all Werewolf roles are excluded from Mafia. (did I really have to say that?)

Werewolves
Normal Wolf - Basic werewolf with no powers save voting.
Alpha Wolf - Able to maul a player once per game, in addition to the wolf night kill.
Beta Wolf - Able to survive a single action that would otherwise kill him.
Gamma Wolf - Able to infect a player and turn them into a Normal Wolf.
Seer Wolf - Able to peek a player each round to discover their role.
ADVWolf Mage - Able to force a chosen player to target another chosen player each round with all actions they perform that round.


Mafia
Goon - Basic mafia member with no powers save voting.
Don - Able to peek a player each round to discover their role.

Pathologist - While alive, learns the roles of all dead players.
Hitman - Able to shoot a player, in addition to the regular Mafia shot, once per game.
ADVFramer - Able to frame someone each round, making them look guilty to the Deputy.

Evil Villagers
Evil villagers win with the wolves/mafia, but don't know their team, aren't detected by the Seer/Deputy, don't need to be killed for the village do win, and don't count for parity.
Traitor - Basic evil villager with no powers save voting.
Sorcerer - Can peek for Wolf/Not Wolf (or Mafia/Not Mafia) each round.

Watcher - Able to watch one player each round to see which players target them with powers.

ADVCult Member - No powers other than voting. Commits suicide if the Cult Leader dies.
ADVSerial Killer - Able to make a kill each night. Wins if he is the last player in the game.
Fool - Wins if lynched. Usually does not cause the game to end.
Survivor - Wins if alive at the end of the game. Can win with any team.

Secondary Roles
Note: Secondary roles stack with a player's normal role, passively giving them extra powers or drawbacks. Hosts may choose wither or not to have a secondary role be known to the player who has it.
Tough - Able to survive one otherwise killing action.
Brutal - Brutal players may retaliate against a chosen player on death, shooting them also.
