I watched a few episodes of it and I'm sorry to say but I didn't find it interesting in the slightest. Rughugger watches some weird stuff. ._. Most of the animes listed here so darn weird. Space Pirates and teacher-aliens are too cheesy for me.
Eat man might be up your alley. It's about this guy who is a bounty hunter and can eat anything metallic and depending on the situation, he can reform that object from his hand at will. This has included large guns, prison cell walls, and even a small personel transport. Kick ass.
