When Robotnik was about to build Omega, he discovered he was all out of metal. So he built him out of pure badass instead.
E-123 Omega is one of my favorite robots. He's powerful, cold and amoral, had an awesome voice, and is obsessed with revenge! I was so angry when they ruined his voice in the next-gen Sonic game. When I saw him, I thought "Yes! Omega is here too!" Then he spoke and my rage echoed across the universe. Sounded like a half-broken Speak & Spell.
Anyway, great picture! Not many people can actually draw Omega, but you've pulled it off spectacularly.
