And, ANB, genjutsu can be broken - normal genjutsu. But resisting Tsukoyomi has different requirements entirely, namely, both Sharingan and Kekkei Genkai (i.e., not Kakashi), and that's resisting it before the fact..once in it, Itachi controls "everything", i.e., omnipotence. Tsukoyomi is stated to take affect instantly, so unless it is met with the proper resistant, instantly, it will take affect. Now, as long as Superman sensed what was happening somehow, then he of all people should be able to counteract instantly, in which case, Superman wins..instantly, by the like..the force of his perspiration, that he has not yet..perspired, but that's not the problem here - it isn't Superman vs. Itachi (since..that matchup, would be horrible..). The problem is, this match places Superman in Tsukoyomi to begin with.
