It did NOT use Pound in the gym battle. Gliscor can't even learn Pound. It was just Gliscor hitting Snover with its tail for gods sake. Chimchar should evolve to be EVEN stronger. Also, in Hoenn, Treecko was doing amazing beating a lot of Pokemon in the gyms and it evolved and same with Grovyle! I mean really, Chimchar is EXACTLY like Treecko/Grovyle.If as a Chimchar he beating the strongest pokemon of two Gym leaders, it doesn't need to evolve. It's allready strong.
Oh by the way, Gliscor did use Pound in the gym battle, ha.
To add to that, Paul had Chimchar since he came back to Sinnoh which doesn't seem to long ago and if you add that t its battles it has had with both Paul and Ash, that is a lot. Oh and a Pokemon doesn't need to have beaten a lot of strong Pokemon to make them not evolve. Didn't Treecko beat at least one of Flannery's Pokemon, if it did, I know that Grovyle beat Winona's Altaria.^ We had Grovyle by the 5th Gym though, so essentially by mid-Hoenn.
Now we're past Gym 7 and we still don't have Monferno.
