Alright then. Time for Act 3, I guess! Can't wait to see these ideas. - STORY - The second human (from Act 2, if you remember) unleashed the power of CORRUPT onto the Scratch OCs. They are now unstable. All other character lore is up to you guys.
While MT!EUC Breath X ("X") was created after Corruption, and as such, is not corrupted, his GASTER was corrupted, and took control of him.
