Dragon Ball Super
Universe Survival Saga
Main article: Universe Survival Saga In the anime, the idea was proposed by Shin, on the basis that the two of them would be an ideal pair for the use of the Potara Fusion. Due to them being twins, it is assumed by Beerus that their compatibility would be perfect for the fusion and would result in an extremely powerful warrior. However, the idea was tossed aside after Whis explained that if the fused fighter were dropped out it'd count as both fighters being dropped out and would result in two losses for their universe. However, seeing as how Zeno and Future Zeno didn't mind about Kale and Caulifla fusing with the Potara to become Kefla, it's extremely likely the same thing would have happened if 17 and 18 fused as well.
Video Game Appearances
Though once again only a concept, Android 35 is brought up when Super Saiyan Blue Gogeta also proposes the idea of fusing with 17 to 18 in Dragon Ball FighterZ, but suggests that with him around, there's no need for them to fuse at all.
- As 17 and 18 are components of Cell, it is hypothetically possible that Imperfect Cell would be able to achieve his Perfect form if he were to absorb Android 35, as they are a fusion of 17 and 18.
