Mr. Reloaded
Cause a pirate is free
Baby Noibat battling Mega Abomasnow equals instant lost. Dragonite was a fully evolved pokemon which is different. Noibat is going to lose the ice gym in it's condition. Anyway, Noibat could learn Gust, Air Cutter or Air Slash since special attacks is what it is good at.
Again you don't know where Noibat will be by that point or what his movepool will look like, hell he could very well be evolved and easily be on par with an Abomasnow mega or not.
Don't underestimate the bat.
