Acceleracers Wiki
The following information is researched by fans and is subject to speculation.

Rogue Hog a.k.a Thunderblade is an unreleased Metal Maniacs vehicle designed by Fraser Campbell. The initial concepts were intended for an Acceleracers continuation, and can be seen in patents for transforming vehicles by Mattel.[1]

The vehicle was patented in late 2005, but was eventually used in 2007 via the Stunt Strikers McDonalds line. It then was released into regular Hot Wheels diecasts.
