Omega Weapon and Nero

[MrSmiley]

Ya that is what Nero did.

Nero escapes and lives to fight us again another time but don't forget he is also a Magitek genius like Cid so it is possible for him to create Omega Weapon

He already has Nora's weapon from RWBY.

ruby weapon as in, like ultima weapon but ruby weapon...like from VII, not his personal weapon for smacking you with
