Mecha Sonic Model No.29

Rocket metal Sonic (Roketto Metaru Sonikku in japan),or also reffered to as "mecha sonic model no.29",or simply as "Rocket Metal" is a character that has only appeared in Sonic the Fighters.He appears in the intro sequence of the game.No doubt he was built by Eggman.He also shares moves from certain fighters (like Knuckles,and a few more)

Look
He looks similar to Metal Sonic,only rocket metal's spines are more longer and more stiffer than metals,rocket metal also has wrench-like hands,and has a "flat" body (rocket metal doesn't have the hole in the front of body that metal sonic does).Rocket metal also has feet similar to tails' shoes.Rocket metal can also transfrom into a rcoket (shown in the intro).

Appearence
Rocket Metal appeared for only aa few split seconds in the inro for sonic the fighters,he is seen flying by the Death Egg,and seconds later transforms into a rocket,he hasn't been seen since that very quick appearence,it is possible he is somewhere far away in space,or was destroyed when the death egg exploded in the game.His fate may remain uncertain forever.
