I mean someone else,he is from the SCP Foundation Universe and is considered the strongest being in-verse (excluding other SCPs that are outside of the SCP Multiverse)

We don't have much information on him but it's pretty much confirmed that he is the strongest SCP inside the SCP Multiverse

He isn't from a comic...he's from an article on a SCP Foundation website

He is stronger than the High Elder Gods,beings that can casually destroy all of creation,reality,concept and basically everything inside the SCP Multiverse yet they are still afraid of the All-Mighty
