Well, it appears to be another bug-type, which is...unfortunate in terms of type, given that gives me two of them and increases the susceptibility to fire, but it doesn't have Abdiel's weaknesses to rock, ice or electricity, either.

As for why I selected it, let's just say that this species likes to greet those who disturb them by exploding rather violently. Outside of that, its defense appears incredibly high - which is, with the exception of Carlisle, admittedly something that my team has a bit of a problem with. Its stats appear reasonable for one so low in level; if it gets an evolution, I think it should do nicely.

[tl;dr - HE'S DONE HIS RESEARCH, YOU JERK, CAN HE KEEP IT]
