How would one establish a grapple and what would the benefits be?

You'd just have to say in the narrative that you were trying to grab hold of someone and then I'd play it from there. I'd be looking to compare the relative Attack and Defence ratings of the characters involved, along with their special abilities, but trying to grapple a boss like Thrash probably wouldn't work.

A successful grapple would result in both individuals being unable to take any actions other than struggling against each other, while the attacker tried to keep the target trapped and the defender tried to fight them off.

If you were thinking about grabbing one of the Cheerleaders, I'm sure they wouldn't mind a little tumble on the rooftop. They're all horny little minxes and a big strong man pinning them down and trapping them in front of everyone could have some very interesting results.

When does downbeat/beatdown wear off?

Either the turn after Thrash is taken out of action or when other special conditions are met, which wouldn't be very healthy for the team.
