What skill advantage does BH have over the dude who's conquered atleast 99 different dimensions? Not so sure about intelligence though BH could probably be smarter since Dagon is overconfident.
Blackheart's a combat genius though. Let me pull up the reasonings
Dagon was able to battle against Sir George in their ancient battle.
Okay, so to clarify, Blackheart had the prowess to defeat Ryu, Spider-Man, Zangief, Captain America, and Chun-Li at the same time. While the last three are certainly impressive, Ryu and Spider-Man are stands out as these two are on the same level (Ryu views Spider-Man as a rival). These two already have some really good feats like defeating Apocalypse, who is a nearly 5000 year old mutant who has spent much of his time alive in combat. But furthermore, Ryu is considered more skilled than the mercenary known as Taskmaster, who can replicate any physical movement/fighting technique simply be looking at it without the need for practice, no matter how complex it is. Furthermore, his analytical abilities allow him to predict attacks and tell if opponents have hidden weapons with a glance. Blackheart's able to take down Ryu, Spider-Man, and three other fighters who are impressive in their own right at the same time
Counted.
