how about an Eclipse, a promethean tank with a similiar, more jaggedy look to the wraith, would have a main dual sentinel beam with a supressor turret, would hover, equivelent to scorpion and wraith, and would explode when hijacked
or a Mercury, a promethean jet/plane thingy like the banshee, looks like a forerunner version of the x-wing. Has a machine gun forerunner style and an dual incineration cannon on the side. obviously flies and would spiral out of control when hijacked.
