Woah, easy there Surfer, you're a 1881x light speedster 100000x planet buster, after all (or something similarly autistic)

And that's not even including guys like Lunatik, Ravenous, Namor, BLACK PANTHER AND KARNAK while giving a lot of people the benefit of the doubt in believing they're more powerful than Ginyu (in all honesty, they probably aren't, Ginyu would be on par with Thor and such in Marvel, it's being modest to put these guys at Frieza level).
Though, that seems to be a list of people Nappa and even Raditz could wipe out, rather than Cap'n Ginyu, perhaps I overestimated the Surfer a huge bit.
How does one determine if someone is Captain Ginyu level? I guess, for starters, they'd have to be able to own Saiyan Saga Vegeta/Rekuum with a single blow/energy blast like he was trash.
Silver Surfer cannot do this, so I suppose, Silver Surfer is not even Cap'n Ginyu level.
