i think he could beat most any who oppose him easily even without the penance stare
Depends on how much Johnny's in control. When Johnny's in control, and the 'safety's on', he's strong enough to go toe to toe with quite a few heroes in strength.
When the safety's OFF, and the Rider's in charge, well... Let's just say there's a reason even the Sorcerer Supreme stays clear of the Rider.
Especially after Strange and Johnny's little staring contest.
