Since you apparently want elaborate answers:

Foxy slows, which enables Mr. 5 to land sure bombs.

Caribou slows/sticks you in a swamp, enabling Luffy to get hits off

Hina cages people, Akainu pwns them while they're trapped.

Smoker holds people Zoro cuts through the smoke into the trapped people.
