Freeze Shock deals damage and has a 30% chance of paralyzing the target.
Freeze Shock does nothing on the turn it is selected, other than state that the user is charging. This charge turn can be skipped using a Power Herb. On the following turn, Freeze Shock will deal damage, PP will be deducted from it, and it will count as the last move used. Once Freeze Shock is selected, the user won't be able to switch out until it is disrupted or fully executed.
If Freeze Shock is not fully executed, PP will not be deducted from it, and it will not count as the last move used. If the target uses Mirror Move during the turn that the user is charging, Mirror Move will copy the move that the user executed immediately before using Freeze Shock (or fail if it can't).
Sleep, freeze, partial trapping, and flinching will pause but not disrupt the duration of Freeze Shock.

Black Kyurem puts its claws together, and a light bluish-white ball of energy surrounded by electricity is formed and becomes larger. Black Kyurem then separates its claws, and the ball is fired at the opponent. When the ball hits the opponent, it freezes it.
This move seems to draw reference to both Zekrom and Kyurem, as it is Ice-type and its name and side-effect are related to the Electric type. Furthermore, in Pokémon Black and White, the animation for the actual attacking part resembles that of Bolt Strike, one of Zekrom's signature moves.
Ice Burn, a move variation of Freeze Shock, likewise references Kyurem and Reshiram.
Along with Ice Burn, Freeze Shock has the highest base power of all Ice-type moves.
