What Happened To Everyone Who Joined The Fantastic Four?

After Namor the Submariner's cousin, Namora, was injected in the womb with her own DNA, she gave birth to her own clone called Namorita. This means that Namorita is Namora's daughter and clone but they are both Namor's cousin. (I know. It's weird.)

Namorita often works with the New Warriors but left when her teammate and boyfriend, Richard Rider, refused to support her. After she met Johnny Storm, the two became an inseparable couple, compelling her to join the Fantastic Four.

While Reed, Sue, and Ben were busy battling Annihilus in the Negative Zone, Johnny learned that Namor was attacking New York City. Since his teammates were occupied, Johnny created an ad-hoc Fantastic Four, consisting of himself, She-Hulk, Ant-Man, and Namorita to take down the Submariner.

Sadly, Johnny Storm has never been known for consistent relationships, and Namorita was no different. After they broke up, Namorita rejoined the New Warriors. Tragically, her reunion with her old gang was short-lived. After a combustible supervillain called Nitro detonated himself while the New Warriors were pursuing him, he incinerated most of the superheroes to ash, including Namorita.
