Li'l Wallaby is the lovingly named Auto-Turret built and customised by Greaser.
The auto-turret was initially non-functional, built by Greaser to assist her in combat situations but lacking a tageting talisman so it could tell friend from foe and accurately fire its twin machineguns. A targeting talisman was acquired by Mach from a dead stable on Buckston's coastline, after Greaser was injured by Ardent Vortex.
The turret proved effective in combat situations and was upgraded with a gatling laser, replacing one of its machine guns. The two different guns allow the turret to adjust its combat strategy, depending on the situation.
