Mega Man X6- Infinity Mijinion (First Pick, No Death)

Mijinion's actually a very good first pick, mostly because his weapon is X's best boss murderer, but also because at Level 1, he can only spawn one of his clones, making him a lot easier to exploit in the way I did. On higher levels he'll spawn more of them so that trick may not work as well past Level 1, which is all the more reason to try and tackle him first.
