Yes, that is a friggin metal version on Roneru... and who madi it? I dunno. It sure as hell wasn't Eggman because he's to busy trying to deal with Sonic. Oh well, let's just give the specs on him.

Model number: RTHMX33079
Code Name: Metal Roneru
Weaponry: 1 Gauss cannon installed in each of the dreadlocks on his head, Anti-magic missiles, Anti-personnel crescent beam, and a tail laser. There is also more than just those weapons installed around his body i think...
Booster model: MVK-88957 <--- Those have to be custom made...I've never seen these in Eulysian markets...

Eh? A bio? Let's see what it says...

Metal Roneru was created for the sole purpose of destroying Cyberntic Roneru and his biological counterpart. His armor is a lot more dense because it has to be able to stand against Cybernetic Roneru's "Devastator Cannon". His custom-made boosters allows him to quickly dash about without overheating. Installed inside his generator is a planetary bomb installed that will explode if he is either badly damaged and cannot move or he is being hacked by his creator's sister.

Dammit...I can't read the rest... I gotta go find my translator...
