Omni Units are also called Dream Units, and if you read the lore of almost every Omni unit it keeps mentioning, "If this unit had survived they probably would have..." and so on, the 6 heroes are dead. But the Omni Versions of them are what could've happened more than likely had they lived or done something different than what their original selves did, read all their lores it keeps saying that. Same thing with Felice, she died, and that death caused the gods to seek humanity's freedom, but her Omni says "It is easy to imagine that if she were still living..." she's dead that's a fact that cannot be overriden, her Omni is an alternate reality of her not being killed.
