Look through the various D&D manuals released over the years.
As for stuff off the top of my head, not just self made but gotten elsewhere too. Not going to include much in the way of sci-fi.
Warriors (tanky) ::: Guardian, Defender, Stalwart, Bulwark, Pikeman, Knight
Warriors (DPS) ::: Samurai, Berserker, Barbarian, Battlerager, Martial Artist (could be tanky), Brawler (could be tanky), Slayer,
Warriors (Support/hybrid) ::: Commander, Tactician, Strategist, Gladiator, Dragoon, Mercenary, Blade-dancer (can be either damage heavy or counter-attack heavy)
Thieves::: Dervish (arguably warrior DPS but squishy), Gambler, Thief, Rogue, Thug, Burglar, Scout, Archer, Marksman, Gunner, Sharpshooter, Crossbowman
Mages (DPS) ::: Evoker, Warlock, Sorcerer,
Mages (Support/utility/hybrid) ::: Summoner, Necromancer, Enchanter, Healer, Diviner, Haruspex, Witch, Wizard, Conjurer, Cabalist,
Hybrids/etc: Dream-thief, Bard, Rune Knight, Cleric, Paladin, Duskblade, Ninja/Assassin (depends), Bounty Hunter, Arcane Archer, Arcane Gunner, Inquisitor, Psion, Beastmaster, Death Knight, Dark Knight, Blackguard, Druid,
I can probably come up with more if given the time.
