"CRUSH! HARD DRIVE!"
Hard Drive is one of the Sentinel's Hyper Combos.
The Sentinel creates a pyramid-shaped forcefield around its body and rams through the opponent, assisted by several mini-Sentinels. Can only be used in the air.
This is a good hyper for Sentinel because it is completely invincible, able to go through any other hypers. If air Rocket Punched is used, performing the Tiger Knee Motion, 5 Hard Drives can be used in a row.
