Ally Law

Ally Law is a British YouTuber with over 2 million subscribers. His channel consists of him and his friends essentially sneaking into places without permission (trespassing, which is not illegal in the UK) for entertainment which leads to them commonly getting into trouble with the police force. For this reason his channel is rather controversial.

In-story he isn't that different, as he works with the protagonists in some cases, films it for YouTube and is described to be a genius escape artist.

He first appears in Chapter 3 Part 17, and sides with the protagonists to put a stop to Mrs Crocker's evil plans, all the while he films the entire experience for a YouTube video.

He later appears in Chapter 3 Part 22, climbing a building as usual. He and his friends are caught by what used to be Ed's army, who try to destroy them. Ally and his friends get lucky and are able to escape, getting on a metro train.
