Suggested by Sonic Omega is a powerful robot who even went up against Shadow for a moment there. If it was more than a moment then he would have been completely doomed but he still has a lot of firepower. Ultimately he will lose against Vile because the latter is a lot more mobile and has enough firepower to breach Omega’s defenses. Ultimately that’s the big tipping point in this matchup and I don’t see Omega finding any way out of that situation. Vile win.
