It's an african-american man with asian features who travels the multiverse in search of life. He possesses three anomalous devices: A tablet that collects extremely in-depth information for every living thing within three meters that apparently has infinite memory, a watch-like device that teleports him to alternate dimensions and large scale teleportation , and a suit that allows him to survive in realities very different from his own.
I was thinking that the foundation discovered him after he created a website where he posted information on various forms of life. The foundation monitored him and seized him after he started posting information of anomalous species both known and previously unknown species to the foundation.
Following his capture, he agreed to be contained within the following limitations: Be allowed to travel and continue his collection of data (both to other realities and this one as long as he returns), regular searches of his tablet for potentially useful information, and being treated as an employee to the foundation.
