Interactions
Does De-Fusion trigger Elemental HERO Absolute Zero's effect?!
Absolute Zero leaves the field because De-Fusion resolves.
Yes. Absolute Zero leaves the field face-up, so its effect can activate.
Can De-Fusion return Fusion Materials that were sent by Future Fusion?!
Future Fusion has sent materials to the Graveyard and you activate De-Fusion.
Only if the materials are still in the Graveyard. If they have already left, De-Fusion cannot return them.

●You may use De-Fusion to Special Summon Goddess with the Third Eye or King of the Swamps if it was used as a Fusion Material Monster for the Fusion Monster selected with De-Fusion.
●After you attack with a Fusion Monster, you may activate De-Fusion in the End Step of the Battle Phase to Special Summon the appropriate Fusion Material Monsters and attack with them in the same Battle Phase.
●If you activate De-Fusion and select a Fusion Monster that was Special Summoned by Magical Scientist or Metamorphosis you can return the Fusion Monster to the owner’s Extra Deck, but can't Special Summon any Fusion Material Monsters since none were used.
