Omega Flowey's Ultimate Undying Revenge

Really though, you're not even really supposed to see this.

 is arguably one of the biggest threats The Gang will have to face. Unlike regular Omega Flowey, has a huge list of powerful attributes that make him even more threatening.

Attributes

 * Killer Robot form(Although, it cannot be controlled and still has it's own mind)
 * Absorbed every single Monster SOUL, along with the Human SOULs and even Chara's HATE.
 * Managed to steal the Master Emerald from Knuckles the Echinda, powering this abomination up even more.

Maybe more later..

Trivia

 * plans to use him as the real final boss if there is ever DLC(No, not the paid content!) or a sequel to the upcoming IaLR RPG.
