You seem to be trying to use CIS as some kind of means to get around a basic thing like "they will remember what their powers are and to use them". None of them are explicitly idiots or incompetent as part of their concepts. There is nothing from that to claim they will fight like dolts or intentionally hobble themselves in the face of something like that.I don't really think so. Without speed, the scenario I proposed would only require them to act with CIS. Superman/etc would use more powers and the fight would be more exhaustive and a lot more detailed but the scenario would more or less work out the same when speed is altogether removed, and CIS is in play. Hulk would end up the guy everyone eventually unites to calm down. How do you think it would go down sans speed with CIS in the Op scenario? What moves happen? What order?
Or Hulk would end up the guy J'onn puts to sleep with mind powers, as opposed to just sort of standing there doing nothing while Hulk apparently beats the crap out of various members of the JLA.Hulk would end up the guy everyone eventually unites to calm down.
