Panther's claws should theoretically be able to harm Cap's shield. Once he does that, the boyscout is out of it. "Old body, old pal, you were like my right arm. Remember in volume three, where I lost you, and referenced your loss in over 20 seperate issues until I finally got you back because of arrested plot development? Yeah, those were good times, oh bother."
There's no concrete evidence to say Cap's a better fighter. He's beaten Panther, while they were being mind controlled. Panther figured this out, and used all of his will power to overcome the control and lose purposefully. He's the living legend of WWII, fighting the good fight since 1941! "Oh please, you spent more years on ice than you ever have fighting the good fight." - Thin Man right before he beats the snot out of him.
I'd rather see T'Challa win.
As I see it they're just about neck in neck. Except for the fact that Cap has the superior strength and endurance. And endurance as I see it is a key factor when engaging in hand to hand combat. I doubt T'Challa could outlast Rogers in a long drawn out battle. ( Which between them you know would be the case. I believe. ) BP of course would hold his own but Cap just outmatches him in those departments. It's a close call...I'm leaning more towards Cap on this one though.
There's a difference between them though. Cap's super soldier serum was artificially made in a lab to enhance his senses not unlike crack. But T'Challa's herb was naturally developing in the Wakandan jungles to also enhance his senses and cure his glaucoma. whistling So as you can plainly see...this has nothing to do with the topic...
Panther is everything Cap is....but slightly better..the herb places him at peak human like Cap, but increases senses and agility...Panther also has the cat reflexes and is far smarter...um im pretty sure BP figured out how to cut vibranium when he made the antimetal claws, BP is a master of using vibranium...vibranium is more rare than adamantium since its a meteorite only found in two places...one is the country Wakanda which BP is sovereign ruler...the other is the savage land.
