I assume it is the versions in the picture, which would give him the full power of the Nova Corps and world mind. Also, you mean to say that Flash the biggest jobber in comic book history has been tagged by WW's lasso.... It's not like he constantly is tagged by much slower opponents during his many years in comic
WW has also tagged Cheetah many a time. She's a speedster too, fast enough to toy with both Flash and Superman (she wasn't out to hurt them, but to get caught).
If Nova doean't have World Mind and full power of the Nova Corps (full nova force) he loses. But I was assuming it was the ones in the picture the op provided. But rest of them wins, with low diff.
Four of them doesn't have to fight close quarters (Surfer, BRB, Ronan, Quasar). Even if it would come down to that, two of the four would beat her (Surfer and BRB).
Ronan beat her due to his universal weapon.
Beta Ray Bill would beat her due to the fact he is not only exponentially stronger and more durable. But also he has stormbreaker which would counter everything WW can do.
Surfer would win because he is the Silver Surfer.
Quasar would win because the Quantum Bands.
Nova (assuming it's the one in the picture) is more powerful than her.
Gladiator would outfight her due to superior strenght and durability.
