Hi !
So here is my entry...
The vehicle mode is a Porsche Carrera GT and since its a Porsche I thought the face should have intakes similar to the 911 Turbo.
After finishing i noticed the face looked similar to X-brawn from RID so that is where the name came from

His weapons are swords that extend from the door halves on his arms (the doors swing forward and out come swords

).
His feet are are wheels much like arcee and sideswipe but contain toes for slower walking and faster breaking.
For the transformation :
The front of the car splits , the hood drops while some of it splits (for the head to come out) and some of the engine parts fold away from the back of the car to become the torso while the windshield halves become the "wings".
The arms are attached to the front wheels from the inside and split out in robot mode along with the doors.
The back of the car splits to become the crotch area as the two back light sides form the front and the spoiler bends above them while the middle area forms the back.
The legs split out along with some of the side of the car and extend while the rear wheels form the feet .
Anyway here it is :
And this is the car its based upon :
