Harold is a default character appearing as the deuteragonist of Project Eeveesauce (2019) and has a minor role in Return of the Eeveesauce. He is usually kind and heroic, but is known to be selfish and egotistic at times.

Canonically, he is the true main character of all RPG Maker MV games in existence, as he is automatically set as the playable character when a new project is created (before being replaced by someone other). This is the reason why he is often jealous of other default characters taking the spotlight.

In Project Eeveesauce (2019)

Harold is first met by Tiny on the small island of Carptown 2014 after she arrives via TOOTER. He briefly explains that he was attacked and doesn't remember anything before joining Tiny in her adventures.

Once they enter the CAS Casino, they encounter Nadroj who is recognized by Harold as the aforementioned attacker. They battle it out and eventually Nadroj ends up joining the team, much to Harold's dismay.
