The Mobile GINN is a great model kit on its own, but if you're looking for more of that over-the-top Gundam Seed flair, then you probably want a couple more swords, some shoulder-mounted cannons, and maybe a crazy helmet. Correct me if I'm wrong but that seems like the direction you'd definitely want to go.
