Do I need to have knowledge on those retarded new pokemon? I only know the classic ones or whatever you call them. Charmander, Bulbasaur, Squirtle etc being the starter pokemon and mew/ancient mew being the most awesome pokemon ever, etc.
Scottie likes legendaries, don't you Scottie? Well you see Scottie, legendaries are special and powerful Pokemon that once defeated in battle and have had a pokemon catching device used (such as a pokeball) on them will aid the trainer. That is how legendaries will work.
