Lupa is definitely a strong fighter but I think she is a little outmatched here. Ridley has size and strength at his disposal so it’s not like Lupa has the edge there. Then you also have to factor in his fire balls and Meta Ridley form. There won’t be much that Lupa can do against such an onslaught and I think she will ultimately just have to take the loss. She’ll put up a fight, but at the end of the day her options are limited. Ridley wins.
