Okay I see it, Ash sees a Raichu and then the next picture Monferno is battling Raichu. That is good evidence that Chimchar will evolve.
Although that may not be the case; it could easily be someone else's Monferno.
Misinterpreting my posts is not your fault, negative repping me, and getting very sensitive about my posts because you misinterpreted my posts however is your fault. Think really hard, before negative repping or making a big deal about my posts. I don't appreciate being negative repped for reasons that are a result of misinterpreting my posts.
