It seems at this stage, Terriermon has finally calm down. Mega Gargomon is the very picture of serenity. However, Terriermon is still very much in there. So while he's not as gung-ho about rushing into fights as his previous forms are, he's still very good at provoking them. Cocky and arrogance in a tin shell sums him up well. Thankfully, he's got the firepower to back up that trash talking. Also don't threaten his partner. Not unless you want a face full of missiles.
