BM being a team back up heavy already implies that he is more powerful than the primary heavy hitter whereby BM is called in when the team is failing to handle a villainous situation.
Also we also get to see BM use his abilities more uniquely when handling exotic science than just punching and shooting beams.
The recent Dr.Doom mini was a great opportunity to show BM use his powers to contain a planet destroying black holes but the writer was ssooooo gung-ho to dumb down BM for whatever hyper-idiotic reason.
