Thor won the Head-to-Heads and were very dominant. The others were all defeated convincingly by the heat winner at some point, whereas Thor beat Shockwave.

This year we have a Sabretooth that was annihilated by Aftershock, Chimera which was OotA'd twice by Eruption, Thor which lost thanks to a mistimed charge, and then again after a long battle to Concussion, Pulsar which came joint top of the leaderboard, but kept suffering massive damage, and finally Apollo who despite being defending champions, struggled to defeat Crackers 'n' Smash, and were comprehensively beaten by Carbide twice.

It should be Pulsar or Thor, Apollo cannot be counted out though.
