They have to have been called a omega class mutant by another omega. uncanny x-men #513 emma frost is confirmed to be an omega as well as xavier. x-men the 198 #2 emma calls mr. m an omega, and uncanny x-men #518 xavier calls emma an omega. if one of these three characters or someone else confirmed by these characters to be an omega has called Exodus an omega and you know which comic then you can list him as an omega but you have to refrence the comic for proof.
