Upon casting, the user starts charging the attack (Anna readies her bow, while Matt assumes his charging stance), while the kanji 悪即斬 (Aku Soku Zan - Slay Evil Immediately) appears on the screen. Afterwards, the attack is then unleashed, striking the entire enemy wave and temporarily blinds the screen in a black-red flash.
Whilst Annihilate has very low power (the lowest of all Limit Breaks in the game, and much lower than most conventional skills) and thus does not deal much damage on its own, it has a very high chance to inflict the Death status on hit targets, killing them instantly. Due to this, the skill may be classified as a "high risk, high reward" type of ability. It is worth noting that most bosses encountered in game have immunity against Death, which makes this limit break essentially useless against them, yet it may still prove useful against some other foes.
In EBF4, Dark Matt can also use Annihilate, and Praetorian's dash attack has similar animation and effects.

Limit Break! High chance of instant death to all foes. Does not work well on bosses.
Epic Battle Fantasy 4
Annihilate returns as a Special Limit Break available for Matt and Anna. As Matt has Ragnarok, which normally destroys regular foes and deals meaningful damage to bosses, Annihilate is better fit on Anna.
