Santa, Rudolph, and Mega-Claus with the first production batch of B.A.D.A.S.S. Mk. II assault robots, modified with Elven technology for increased firepower and performance.
The Scout unit's plasma cannon remains unmodified, but its targeting laser has been upgraded to a 431N-D33R "Rudolph" bioluminescent target painter and slaved to a digital INN (Identification Naughty or Nice) system.
The Strike unit carries a massive rail gun and a millimeter-wave targeting radar. Santa's elves have upgraded the rail gun to fire sub-caliber tungsten penetrators with an incendiary carbon coating, allowing it to neutralize basically any vehicle with a single well-placed shot.
The Assault unit is armed with twin miniguns for close-in firepower. Even Santa's elves can't add very much to that.
