U33

U83 is a Callum Morrin variant, he is the creator of a video titled "please put any new info on the wiki we need to sort this - u33".

There is little to no information regarding U83, although he seems to have access to a version of the Callum Morin Vlogs Wiki. However, it likely is a completely different wiki to this one, given he is in another universe that does not typically share the same internet. It is also assumed that he is aware of the other Callum Morrins on the heyguycallummorrinvlogshere channel, however the assumption is based purely on the screenshot provided by the Callum Morrin anomaly variant who uploaded the U8 death footage.

U33's intent to create a wiki is strange given the obviously impossible nature of collaborations between multiple Callum Morrins outside of the heyguyscallummorrinvlogshere channel.

Appearance
The appearance of U33 is unknown.
