The Vermin

That guy.

The one nobody wants to be around because of how annoying they are. Being the non-adventurous counterpart to the Pest, the Vermin is viewed as an antipathy that anyone in their "friend" circle, likely the Main Cast, will secretly avoid as to not hurt their feelings. Because of this, the Vermin is completely oblivious to the fact that nobody really likes them. As a result, they will continue their terrible behaviors, which continue to get on the nerves of everyone around them.
