I really need to check out Annihilation
Started Hickman’s Secret Wars and it hasn’t kicked in yet

So there's Gladiator, the Surfer, Ronan, Beta Ray Bill, Nova Prime, Ikon, and Quasar.
Putting this into perspective.
Gladiator can't beat Superman, but he can hold him for prolonged periods of time.
The Surfer has the power to manipulate energy, and alter genetics. He also has one of the most diverse power sets in comics. He's a threat on his own.
Ronan can turn matter into a variety of things with that hammer. Could he make Superman's costume into something far less flexible? Could this be a way of hampering his attributes?
Would Bill's strength, powers, hammer be enough to help Gladiator hold Superman?
Quasar can analyze a character like Superman, and drain the solar energy out of his cells, and with the Surfer's help this tactic seems to be a sure win. Quasar did shut down Carol in Binary form after all.
Ikon... Don't know enough about her, but is she even needed here?
Nova Prime can add his power to help Bill, and Gladiator subdue Superman.
Just looking at what's stacked against him, and if asked if this team would be enough combined to arrest Superman, I'd say yes.
Or, Superman flies around one shot KOing this team. I'm not really in favor of this outcome for more reasons than I care to go into, but whatever.
