Simple, in the beginning of the game, Professor Elm gives you a choice of Chikorita, Totodile, or Cyndaquil. If you didn't select Chikorita, you can try and trade it over the Wifi Trade Center.

Only you, your rival or a friend who also has that platform can have chikorita.
Your rival will have Chikorita if you pick Totodile as your starter pokemon.
