One of the gunpla I got for Christmas, the ReZEL.

First appearing in the Gundam Unicorn series, the ReZEL is a Anaheim Electronics-developed mobile suit created for the Earth Federation Forces as a successful product in developing a mass-produced version of the Zeta Gundam. Unlike it's predecessor, the Re-GZ, which uses a Back Weapons System, the ReZEL uses the concept & simplified transformation of the ZII & the Methuss, also sharing the same internal components of the Jegan. As it is a transforming MS, it can transform into it's "Waverider Mode", which turns it into a formidable space fighter. One known pilot for the ReZEL is Londo Bell pilot Riddhe Marcenas.

Weapons-wise, the ReZEL is armed with vulcan guns, forearm-mounted grenade launchers, beam sabers, a beam rifle, and it's shield equipped with a beam cannon. The ReZEL can be eqiupped with a Defenser B-Unit backpack, for first-strike attacks on the frontline or at enemy strongholds.

The ReZEL currently has no known successor units, but among it's variants, are the Commander Type, and the Type C units used by the EFF Dogosse Giar-class battleship, General Revil.
