Suggested by Dinosaurroars Alastor may not have the most combat feats around but he does have his super form and fire projection. I’d say that this will be enough to claim victory here. It’s hard to see Scooby Doo being able to keep up even if he was once worthy of the yellow power ring. Scooby has no battle instincts and just isn’t very good at combat. As a result he would be quickly overwhelmed here. Alastor (Hazbin Hotel) wins.
