Not the far in the game,but:
My highest level Pokemon in B/W so far. Too bad it won't help with Elesa..
I at first caught him just for the pokedex..but his barrage of fire attacks helped me a lot in my past attempts to beat Elesa.
Like Inferno,I origanally caught this for the Pokedex. However,when seeing its unique typing of bug/grass I'd never seen before,I kept it and found a tm for solar beam,making me decide to keep it with me throughout my journey.
My last permanent member so far. I went back all the way to Route 3 just to find this and evolve it into a Zebstrika. It ended up learning way more moves then I thought it would and is all and all a pretty good pokemon.
(not permant on my team,or some I sometimes use)
Mostly for using in the fight against Elesa. Still a surprisingly good pokemon. I don't plan on raising it much though.
Just like Ivory,is actually a kind of good pokemon,and I'm mostly using it in the fight against Elesa. They are both probably going to be HM slaves.
I love all my pokemon! But I definatly want an Absol and a Kirlia too.
