BFS - Karol's sword and hammer weapons are pretty gigantic considering he's like... twelve. Clint also uses a gigantic axe/sword thing. (note: "BFS" stands for Big Fuckin' Sword XD)
Boobs Of Steel - Judith is pretty large... And easily the best female at melee combat.
Conveniently An Orphan - Erm, entire main cast, anyone?
Deadpan Snarker - Yuri, who may as well be a younger version of Jade Curtiss. (<- WHUUUUT???! >:O NEVER! They aren't even in the same universe in terms of snark.)
Dirty Old Man - Also Raven, although he does have standards  (pffft, yah riiite.)
The Exit Is That Way - Occurs during a skit at Baction. Karol can't manage to read the map that he made. Judith comes to the rescue.
Expy - Flynn◊ looks a lot like Guy. (wtg Namco character designers <.<)
Foe Yay - Zagi seems a little too obsessed with Yuri...
Gratuitous English - Yeager in the Japanese version speaks English. (WHUT? seriously? Hmm...I need to look this up...)
Keep It Foreign - Yeager speaks English in the Japanese version. So to keep up with the foreign trait, he speaks with a German accent in the American version, ja?
