Demon Sqeegee is a form of Sqeegee, He is not the most powerful form of Sqeegee, but attacks can go through him and he can shoot powerful
lasers that can blast Weegee and friends.

Unlike most forms of Sqeegee, this is his actual spirit instead of just a regular form, and so, being dead, he cannot die, unless he is brought back to life. Sqeegee's spirit was put to rest in the Rise of Sqeegee 6 when Sqeegee died but came back angry in the Rise of Sqeegee 7.
