I think T Gaank is high up there. Very high stats, double protection, and really not much vulnerability to neither SOA nor SOB. I haven't faced him much so far but I'm thinking he might actually top Dagg...
1. Dagg (that +12 is just great and has pretty solid stats to boot)
2. T Gaank (Just love how solid he is)
3. X-0DUS (Strong but not as solid and that could cost you matches)
5. Heegrn Cr
