He made it himself, he planned it himself, he is brave enough to set out and fight the monsters alone, even if the girls weren't gonna help in the first place. But now they're on board, they wanna be control freaks about it and stop him being involved at all. All that preparation, planning, Thrown in the bin because they decided they wanna be the heroes. Yeah, right. Talk about a lame excuse to villainize the only boy in these suits of armored gear.
They even started making him spout that he doesn't care about the civilians. Why are they trying so hard to make him a real dick? I'll tell you why, they want the thought of guys fighting these things in those weapon suits GONE. Guys aren't allowed to do it, it's annoying as hell. Just convince him to put some armour in instead and then have him join their cast, it would have been so cool to see a guy one amongst them.
