Ansgar from Germany, Storm from England and Tornado from England.
I dont think Ansgar will survive very long. My guess is either Storm or Tornado.

Typhoon from England, Tough As Nails from Holland and Rawbot from Sweden.
Typhoon is already out, but the armour on Rawbot wont stand up to Tough As Nails.

Spartacus from USA, Supernova from Sri Lanca and Hard from Belgium.
Ill go for Supernova in this fight, without any doubt.

Crushtacian from South Africa, Snakebite from Switzerland and Pulverizer from Holland.
Im not sure about this one, but Pulverizer is likely to be the winner.
