Bulldog Breed and Robochicken VS Bigger Brother and Major Tom III: The champions FTW.
Firestorm V and Scorpion VS Spawn Again and Comengetorix: Firestorm will probably edge this fight in favour of the underdogs, however if Comengetorix doesn't break down, then Spawn and the former Vercingetorix will win. And I don't thing Comengetorix will break down.
Pussycat and Diotoir VS Rick and Ming Dynasty: Really? The Extreme 1 champs through.
Stinger and Nasty Humphrey VS Naplam II and Sir Chromalot: Napalm is past its time. Sir Chromalot is more of a comedy entry, so I'll say Stinger and Nasty Humphrey.
Drillzilla and Tut Tut VS Thermidor II and Cerberus: Drillzilla can pit both of them. Drillzilla and Tut Tut through.
SMIDSY and Sump Thing VS Velocirippa and Mighty Mouse: SMIDSY and SUmp Thing through.
Rocky Bot Boa and Black Widow VS X-Terminator and Mega Morg: Rocky Bot Boa has very good pushing power, and both Velocirippa and Mighty Mouse are lightweight. The Americans through.
Barbaric Response and Hydra VS Steel Avenger and Lightning: I'll go for Steel Avenger and Lightning.
