Well obviously it had to be Neffy.How is that possible? I love Neffy too, but there's a reason we call him Neffy (Although it was pretty satisfying when he began acknowledging Ratchet as a threat).
I vote for Qwark in GC.Qwark? He was an idiot lol and in no way at all felt like a threat to me.
Qwark took over Megacorp, fired all the employees, transported Ratchet and Clank to Bogon with no way of going back, created one of the fearest beasts in the Universe and killed that Infobot girl. All just for fame.
Pretty damn threatning if you ask me.
Now officially addicted to League of Legends.
