Good answer Ant.
However, for X.A.N.A's case here, what puts him at either 3-A, High 3-A or even 2-C is whether or not the Virtual Universes and the Super Computers from Code Lyoko opporate differently or the same as the real world, making them different or the same space-times
And at the moment, there's more that implies they act differently then real-world time. The most recent example I made, concerning the Super Computers, being of that. Because, for a second, lets say for intents and purposes that they do opperate the same as Real-World time. If the Super Computers opperated the same as real world time, why dont they get revived when Return to the Past is activated? There's no evidence that any Super Computer in the verse has the same Time Reversing function like Franz Hoppers does, so there's no reason at all to assume Time Reversing can't easily affect them. And yet, when Return to the Past happens, those super computers and the virtual worlds they support stay destroyed.
In addition, if a simple Time Reverse could affect the Super Computers Xana ruled, aka revive them back, then I highly doubt Jeremy and Aelita would just randomly do Return to the Past after every XANA attack at that point on without thinking it over first. About not considering the possibility that the Replika's and their super computers that Team Lyoko has worked so hard to destroy would be revived back with just a simple Return to the Past. And unlike everyone else, Jeremy and Aelita take Xana's actions at face value first before anything else. They arent oblivious to his motives and plans and what he'll do to get them done. Plus, if the Super Computers were able to be revived from the Return to the Past program, then Jeremy or Aelita wouldve confirmed it to the other Lyoko warriors and would go back to try destroying them instead of just going on to the next Replika. So, since they launch the Return in time jump just fine without any worry over the computers and worlds they destroyed, and they don't notice and/or confirm any super computer being revived by the trips back in time, it strongly suggests that the destroyed super computers and their worlds arent affected by Time Manipulation in the real world, meaning they act differently.
