Introduced	Generation 2

Rollout deals damage for 5 turns, doubling in power each turn. The move stops if it misses on any turn. If it doesn't miss, Rollout will deal 30, 60, 120, 240 and 480 base power damage each turn respectively.

If the user has used Defense Curl in any previous turn (without switching out) then Rollout doubles in power, i.e. it will deal 60, 120, 240, 480 and 960 base power damage respectively.

As Rollout has 90% accuracy, the chances of it being successful for each turn (with normal Accuracy/Evasion and no other interruptions) are 90%, 81%, 73%, 66% and 59% respectively. In other words, roughly 3 out of every 5 times Rollout is used, it will hit for the full 5 turns.

When a Pokémon is holding Rockium Z and uses its Z-Power, Rollout turns into Continental Crush and has base power 100.
