LOL, Treecko could easily be as strong as Pikachu, there is no rule against that.
Unevolved =/= weak. The kid might be hiding some powerhouses, you never know.
I'll bet almost anything that Treecko will beat Pikachu if they battle, unless of course the kid with the Treecko isn't the main rival of the series.
