Master Asia's secret handshake:
Still the best.
(Also: Sheesh, Rain, do you need to sound quite so ditzy? Not that Domon's ever any better. "Gee, could that guy who is wearing Master Asia's clothes and using Master Asia's martial arts skills to fight giant robots maybe be Master Asia?")
Friendly reminder: In G Gundam, the characters were martial artists who piloted giant robots and fought zombies piloting giant robots while also being involved in a martial arts tournament that used giant robots. And fought a giant robot that was the devil.
