Vent

"...okay I really don't think I shoulda done that."

Metal Sonic 55, Neometal class -- a.k.a. Vent Mecha. A renegade Eggman robot with the ability to mimic any person as long as he knows what they look and sound like, maybe even less than that. No info can be found on him, and even his own answers are spotty at best. He's usually in the form of a brown Mobian porcupine, and dislikes it when his true nature is mentioned.

His theme is Shatterhand by Silent Debuggers or, alternatively, Speed Strike by Kitsune^2.

Personality
For being a horrible death machine, Vent's actually a pretty easy-going guy who enjoys screwing with people and hanging out. He has an odd need to constantly keep himself entertained; failure in doing so usually ends in shenanigans. It's nearly impossible to tell that he's a robot unless he reveals himself-- his personality and antics are way too lifelike. If his claim that he was a real Mobian once is true, then it makes sense.

Relationships
Vent spends most of his time bumming around Tail's house-slash-workshop, and is Copy's close friend. He usually finds himself mediating when Tail and Tide fight, or when Tail decides to beat up Copy, or... okay, Tail gets mad a lot, and Vent's job is to stop him from using any of his WMDs. He's managed to befriend Wayne, and somehow managed to do the same with Sonic and Amy-- a definite surprise, what with Sonic usually scrapping any Eggman robots he encounters.

Other Info
Vent's really not a fighter, instead opting to solve issues peacefully. After enough damage is dealt to him or if someone does an override, however, he goes berserk. His arsenal includes just about everything: swords, handcannons, lasers, etc.-- and because he's made of liquid metal, any severe injuries can be 'healed'-- he can even survive having half of his body exploded, and has. His one weakness is his Chaos Emerald-- without it, he can't keep himself stable. He's obviously incredibly possessive of this for that reason, and gets pretty pissy at anyone who asks for it.
