A.T.T.T.W.I.
QUARTER-FINALS
DR IVO ROBOTNIK VS Ming Higurashi
Time to fight magic with magic methinks. For this round, Ivo will try extending an olive branch to his old partner, the ebil wizard Ixis Naugus. This fellow can turn your body to crystal and give you a slugs head just by clicking his fingers. Basically, Naugus will tackle Ming head-on while Robotnik sends in the SWATbots for back-up.
If Naugus declines however (understandable, given that Ivo trapped him in another dimension for 10 years or so ), Ivo will send in wave after wave of SWATbots and attack from overhead with one of his many lovely airships of doom.

Lord Doomforall VS Professor Vengeance
And here we go again.
Tactics? What tactics? Get as many of my robots and mechs as I can out there and go all out. If possible, Ill call on my allies. Buttnik, The Daleks, the Wootinator, the rogues of Gotham; anyone. Just three words: crush, kill, destroy.
If forced into close combat, get whatever sort of shield I can and use every function the cane has to offer.
