Chikorita is rubbish against the first two Gym Leaders, so I'd avoid using it unless you have a strong team to back it up.
Cyndaquil (that's its name, Katakoe) is good for the first part of the game, but I find that it isn't that strong for the last bit of the game.
And why did you name your thread Simple Questions? Theres a sticky called that and I'm sure lot of people will get this thread mixed up with the sticky.
So please use the REAL Simple Questions thread next time. Thank you.
