How does one go about judging how powerful Cytorrak is? In one comic it said that he was on a rampage and, had to be banished to the Crimson Cosmos because he was going to destroy reality, and this was because the ancient deities could not stop him. Then Juggernaut pwns his master in one of the most CIS filled comics ever written??? Could it have been another Darkseid thing that it wasn't the real Cytorrak, but just an Avatar or Herald of the deity?
At any rate if Juggernaut got his hands on Firelord he would kill him. Thor's beaten Firelord, Hercules has shown that he can take the heat of a greater flame wielder than Firelord (Frankie Ray aka Nova) and Cain has better body armor than the two combined.
