Absolem

Based off Disney's Blue Caterpillar from Alice in Wonderland!

Once close with Alice. She was killed by the Queen of Hearts which caused Absolem to become so distraught and angry that he himself killed the queen and now acts as a ruler of Wonderland.  He just kinda chills in his little mushroom forest most of the time. He blames himself for Alice's death constantly, and his entire personality changed once he murdered the queen, to the point that everyone usually tries to avoid him.
