Abyssmash

The Abyssmash (アビススマッシュ Abisusumasshu) is the Strike Vent weapon of Kamen Rider Abyss, summoned by the Strike Vent card of Abyss's Advent Deck. When activated, the Abyssmash fires a powerful pressurized blast of water at the target or in some cases a tidal wave. Presumably, it can also be used at close range, as the "mouth" of the gauntlet weapon has razor sharp teeth to "bite" the target.
