a mother fucking dragon, summoners use them as a weapon in ff games. Or if we are being picky, a sword. Notable swords include: Cloud strife's buster sword, Sephiroths Blade, Nightmare's soul edge, Siegfried's Soul Calibur. Any sword is good really, best melee weaponary ever. Gun wise, I am a fan of incredibily powerful sniper rifles. Also things like the cerebial bore, the plasma cannon (duke nukem 64), explosive shotgun rounds (also duke nukem 64), Revolver ocelot's revolver in mgs3. Basically i like alot of weaponary, It generally goes in orders for me...
