Deep Submerge is an extremely strong and powerful sea/ocean-based attack that Sailor Neptune used in all versions and evolved Sailor forms in which she appears. In the Cloverway dub, it adds Neptune to the original attack name as it calls this as Neptune Deep Submerge.


Deep Submerge is first used in Act 29 against a Daimon that was about to harm Sailor Chibi Moon and Tuxedo Mask. It appeared as an energy blast that was shot towards her enemies.

First Anime

Deep Submerge is first used in episode 90 (although it was unnamed until her first named appearance in episode 92) against Daimon Mikuji.

To perform the attack, she lifts her arms above her head and brings them down, sending a ball of blue energy shaped like the planet Neptune towards her enemies. It's also possible that water is also a component of this attack, as Eudial's Daimon Chokokka and her animated sand statues were melted by this attack in episode 107 of the anime.


She attack only appeared once in Crystal, it is unknown how it is performed. However, the energy blast has the shape of "ringed sphere" like the original anime. It was used to counter Mimete's attack, preventing it from striking Sailor Chibi Moon.

Video Games

Deep Submerge was performed always by Sailor Neptune in the video games:


  • The attack was renamed "Neptune Deep Submerge" in the Cloverway English dub but in the Viz dub it retains its name.
    • Deep Submerge seems to emulate the crushing force of deep sea pressure.
    • Unlike Sailor Mercury’s attacks, which utilize water itself to strike enemies, Deep Submerge seems take energy from the ocean itself to attack (as seen midway through the attack, when Sailor Neptune gathers water from the sea around her only to convert it into energy). However, it’s also possible that water is still a component of the attack, as seen with how it affects certain targets.
    • Like World Shaking and Dead Scream, Deep Submerge takes the form of a planet (presumably Neptune) to attack the target.  
    • The kanji characters “深水没” (Shinsuibo) associated with this attack in the manga mean “deep water drown."
