First up-

Marauder, a tank-like and predominantly anti-spinner design for the Middleweight category, with a focus on thick armour, great power, traction and reliability from its armoured caterpillar track system, and good weaponry for its purpose.
It's armed with a powerful Reinforced Lifting Wedge electrically-driven by Linear Actuators on both sides, allowing it to function unhindered either way up, as well as a pair of tungsten-tipped Ramming Spikes at the rear.
On a side note, its track-based design allows it to run unhindered when inverted, climb up steep inclines and over opponents when its wedge is raised, and even lift its own front end off the ground with its weapon- no idea how I'll use it, but probably as a victory pose.
And what more can I say? Marauder!
