My original 6 were Venusaur (Blarg), Dodrio (KFC), Dugtrio (HolyMoly, yes I know, terrible pun), Gyarados (Fluffy), Flareon (Blaze, generic names FTW), and Alakazam (MindFreak), before I dropped the stupid cartridge into a puddle. (R.I.P. my Blue Version.)
(EDIT: I forgot about the nicknames, so here they are.)
