Chikorita, Cyndaquil, Totodile = Balanced self as he learns that he needs to focus on other things too:
Chikorita = Ash is strong, but he realizes that he needs to grow.
Cyndaquil = Blazing passion (fire) to be the greatest Pokemon Master of them all.
Totodile = A force that's slowly putting that "fire" out, while keeping it at a healthy size.
Treecko = Ash is stronger, but he realizes that he still needs to grow.
Naetoru = Same as other grasses. >_>
