1. Duh... He's the representative of FNaS1 and overall a titular Antagonist and the Main Mascot of Fiercy Forces in Sonic's Hero Tera Pizzaomnia. Obviously he's the best!
2. Just a slightly injured Clone Sonic with some bandages wrapped on his hands and legs.
3. Aka. "The Destroyed Clone". I don't think I need to say anything here, plus... this guy has two hands in this version. Not One... But Two!
4. Hmm... a darker looking vampiric version of Sonic who likes to scare and feed on Silent's "The Player/Avatar" fear. Meh... Just like the others.
5. Total massacre... worse looking appearance, than Salvage Sonic "Storage-Up!" ... He still has two hands.
