Giant clawed red hand that grabbed The Joker at the end of the Sinister Smiles Arc.  We know nothing about it except for the words it spoke as it grabbed Joker: "YOU HAVE FAILED ME, CLOWN!"

Additionally, the voice appears in "The Laughing Disk- Hired Ha-Ha-Help".

Cheerful, whimsical, Creator of Emulator City, and very high-pitched. Elanif comes with many surprises when it comes to the power they possess. From opening portals, to teleporting, to transforming their body, to communicating telepathically, there seems to be no limit to Elanif's powers. Except of course, the fact that they can't leave Emulator City.

Elanif tells you that they do not know who else is opening up portals across the multiverse, and that it is of upmost importance to find out. While this ask seems to come from a place of genuine feeling, you can't help but feel like Elanif isn't mentioning the full story.

Large blue wave that swept up Infinite at the end of The Infinite End Arc. It was able to speak, consume and transform the Ender Dragon into the Chaos Dragon, turn into darts which killed Johnny, and seemed to be the same color Infinite radiated when not using an item.
