This is Undertale Boss Fight 4 (the last one... not!) GREEN FLAG to regret your decisions ARROWKEYS to move your SOUL
introducing my O.C: Coury! (using Courier New) He's the "cousin" of Sans and Papyrus, and lives in a canonically-unreachable part of the Underground. Also, ALL art done by me (except Coury's head: I used Sans's head as a reference, and then did some revamping) also the Gaster Blaster is not mine
