Bobby has always been an omega level mutant. He just didnt use his powers to the fullest. I know, i know, i know!!! I'm one of those, who are usually explaining Omega level to others, so no lessons needed. (Btw, "they" do not have the same power level, which would be an actual expression of that power, but the same power potential!)
With normal Bobby i meant the Iceman of that time when he was not able to turn completely into ice, send his consciousness through water molecules and resurrect himself from disembodyment. I was talking of the powerlevel "pre X-Men Forever"-Iceman expressed, the Iceman he was most of his career - normal Bobby.
