MCU Lady Sif replaces Captain America in his movies. Does she succeed?

Pretty sure she can do it

How does she fare against Thanos?

Sif clears. Her pure strength is several times greater and her durability is comparable, if not slightly superior. While Cap is an amazing Fighter, potentially the best in pure H2H on Earth, Sif had been alive for centuries and fought different races and fighting styles that Cap has not.

She does it with ease

bump

Nope, she lacks the leadership qualities and ability to bring together or uplift the team like Captain America. There is more to Captain America than simply brute strength. His true power is his heart, the reason he was chosen for the super soldier serum.

Was initially going to say no, then I thought about it and I'm hardpressed to thing of a fight that would test her like it did Cap. The mighty asgardian can do it

@heisenberg57: OP just says she has to perform as well as or better than cap in his fights. Nothing about the plots of the movies.

So yes, she would succeed. Easily. She is one of the greatest warriors the nine realms has ever known and has over a thousand years of experience. So she's on par in terms of skill. In terms of stats, she has superior strength and durability to Cap and a better healing factor. Has impressive speed/reaction feats as well.

She does it with ease all to thanos , don't know if her sowrd can harm him she clears,

@ashketchum93: The post asked if she succeeds if replacing Captain America in his movies. The answer to that is a no. Just talking about fights is a poor representation of Captain America's role in his movies. He's not just some wooden block that punches things. Sure she's strong, but she's not leading the avengers to victory, that's for sure.

Thanos kills her...Ultron knocks her off the truck and she never catches up...may do worse against Black Panther and get clawed, and may do worse against Red Skull and Hydra due to disintegration guns. I guess she'll do better against Loki, but it's not like Sif outclasses Cap in everything.
