Oh and for the sake of the threads purpose, I actually kind of suspect that Luxio will forever stay in its middle stage, while Heliolisk returns as his electrical powerhouse after the gym battle. I also think Bunnelby will be the only team member to actually evolve..
Diggersby, Chespin, Luxio, Dedenne and Heliolisk would be a pretty cool travelling team for him I think..
Truthfully, i don't want
Clemont to take
Heliolisk with him after the 5th Gym battle. I mean what use would it have, its already a fully evolved pokemon. Also who would be the main pokemon for
Clembot to use against the challengers. And
Clemont is probably going to get that
Luxio which i believe might actually evolve to a
Luxray.
This would be more possible if
Luxray gets a Mega Evo, and truthfully presently i only see
Clemont as the possible candidate for getting a "Key Stone". The chances are more for him because of his father who is already a Mega Pokemon users (especially considering the fact that he may actually have 2 Mega Pokemons with him i.e.,
Mega Blaziken and possibly a
Mega Ampharos as well). On the other hand, the writers like to showcase
Ash as an under-dog, so his chances are a lot less (unless
Pikachu gets a Mega Evo).
Another factor to note is that
Luxio might actually be a pokemon related to
Clemont before he got his
Helioptile (which eventually evolved to
Heliolisk).
I want the groups team to be a fresh one and not contain any already trained pokemon, because having something like that wouldn't be beneficial to anyone (aka.
Charizard during the Unova
EN &
DA arc). If needed, he can get another pokemon (maybe belonging to a different Gen, though not considering a 6th or 4th Gen one) later on in the series.
