Ok so
1. Colosseum Entei/Suicune/Raikou they just look amazing. Idk why they changed the colors of them in later games.
2. Basically all the pink shinies I just think they’re really really cool, dratini mareep line, bellossom, lopunny and furret comes to mind
3. Mew esp the faraway mew event in gen 3
4. Fennekin line I love that it looks like a black mage
5. Charizard ik it’s a basic answer but the black just looks so amazing and sharp. Drool
