A Yu-Gi-Oh!spell card that summons a level 5 or lower fusion monster. It looks like a green instant cup noodles with the word "Fusion" written on it. There's a running gag where monsters on the Forbidden List that abuse this card for their Special Summons are slurping the ramen.
In March 2026, a limited timeNissin Cup Noodle version of Instant Fusion was released, with the outside rendered like the spell card, while the inside is just a regular Cup Noodle.
