yeah he can channel his energy inwards but it takes effort, and a little bit of time, long enough for someone to engage him, and he a bad ass, one long very loud scream, and he could wipe out the battlefeild and most probably everyone on it
Cap.America vs BP = cap is the better leader IMO, making him a better asset than BP. Also, his shield is a good defensive item that can allow him to survive against high tier characters better.
Hyperion vs Blue Marvel = Hyperion has better "feats".
Iron Man vs Dr Strange = Strange wins and is more versatile.
Hulk vs Black Bolt = Every single fight Hulk and BB has was more in favor for BB. WWH beat a Skrull BB and his range allows him to be pretty deadly. But Hulk is a better asset as he is more suited for single combat than BB is (BB's voice can hurt his teamates, too) w/c is very helpful in a big melee like this. BB would get stuck using his less powerful abilities.
Thor vs Surfer = Thor is a better asset than Surfer being usable as a front line character while Surfer is more suited for run and gun. Team 2 has very few weaknesses the Surfer can exploit, as well. And Thor would beat Surfer 1v1, too.
Ms.Marve vs Namor =Ms Marvel's energy absorption is a better asset than Namor.
Equal lineup in power but the overall synergy I can see in the Avengers having their top tiers in the front line, great defensive capabilities, having the better leader and years of experience with teamwork will put them ahead of the defenders more often than not.
