While serving as a member of the Nova Corps on Xandar, the entire planet was attacked and destroyed, leaving Richard Rider as the only surviving member.
In order to preserve the history of Xandar and the Nova Corps, he winds up being “uploaded” with the Xandarian Worldmind, a living super computer.
This gives him instant access to incredible amounts of information, but it’s also an incredibly important responsibility and burden that he carries.
Instead, it would actually be much more likely that the Marvel Cinematic Universe would adapt the most recent version of Richard Rider, who experienced some rather intense trauma a little more than a decade ago during the Marvel Comics event Annihilation.
