"Fires two disc-shaped Ki Blasts that cannot be guarded against. The disc will fly out in a V shape and deal damage regardless of whether or not the opponent is guarding."
The user creates two energy disc and fires then at the opponent one after the other in a pincer maneuver that makes it difficult to dodge both of them, as the discs are coming towards the opponent from both sides. Even if one of the disc doesn't connect with the opponent, the other usually will. It can be seen as an improvement over the original Destructo Disc. Like the single Destructo Disc, the this technique will damage the opponent regardless as to whether they are guarding or not.
Double Death Saucer
Main article: Death Saucer
A double homing energy disc attack used by Frieza and his altered clone Perfect Cell. Unlike the Double Destructo Disc the Double Death Saucer can home in on an opponent tracking their movements making for a far deadlier attack. However this advantage comes at a price as it is more dangerous to the user as there are more than one disc to keep track of and should they get distracted they could be accidentally hit by one of their own energy discs like Frieza did during his fight with Super Saiyan Goku which resulted in Frieza being vivisected by one of the discs, though he survived (albeit severely injured and his body in pieces) thanks to his race's ability to survive horrific injures and still live. Perfect Cell can also use the technique due to his possession of Frieza's cell.
Hell Lightning Cutter
Main article: Hell Lightning Cutter
A variation of the Double Destructo Disc used by Super 17 (w/ Android 18 absorbed) in Dragon Ball Heroes. Super 17 first put his hands in front of his face and then he extends his arms to create balls of energies coming from both the palm of his hands. These balls then turn into discs, much like Android 18's Double Destructo-Disc and Android 17's Side Bridge differing only in color and power. Super 17 throws these discs and before hit the opponent, they merge into each other, forming a much larger and deadly disc, ultimately reaching the opponent and striking one for some time.
Z-Assist Dual Destructo-Disc
A variation of the Double Destructo Disc used by the Future Warrior in Dragon Ball Xenoverse when performing the technique while Android 18 is their current Master. The Z-Assist causes 18's soul (which appears as an astral projection of Android 18 performing the technique) to go into the Future Warrior's body while they're performing it increasing the power of the Warrior's Dual Destructo-Disc.
Video Game Appearance
In Dragon Ball Xenoverse, this technique is called the Dual Destructo-Disc (not to be confused with the Dual Destructo-Disc team attack used by 18 & Krillin in Dragon Ball Z: Supersonic Warriors 2) and is one of Android 18's and Future Android 18 ultimate skills. If the Future Warrior takes Android 18 on as a Master then they can learn the technique at the end of 18's training. After obtaining the skill, if 18 is the Future Warrior's Master and the Future Warrior uses the Dual Destructo-Disc in battle it will receive a Z-Assist.
In Dragon Ball Xenoverse 2, Dual Destructo-Disc returns as one of 18's Ultimate Skills which can be learned by the Future Warrior by completing School Quest: "Lesson 3" of 18's Training. They deal damage regardless whether the opponent is guarding are not, making it useful for bypass an enemies guard.
