[quote name='Sir_Fragalot']I recommend using a Gengar simply because of Hypnosis. If you are using Golbat, Raikou can use thunder based attacks and kill Golbat because of weakness. Hypnosis will allow you to get some free attacks in. Just remember once your pkmn with mean look dies, it can flee again.[/QUOTE]
Hm, never even got to battle Raikou or Entei. Just kept encountering, throwing a Pokéball, and watched it flee. Caught Entei with a Quick Ball, and Raikou with a Fast Ball, in the end.
