Seelos was a member of the Dai-ai species in the 24th century, from the planet Naia VII.
In a parallel universe in 2368, Seelos greeted Commander William Riker, Lieutenant Commander Data and Lieutenant Worf of the USS Enterprise-D when they visited the Starfleet Corps of Engineers mining operation on Naia VII, after Captain Ochoa introduced them.
Later, following a flooded mine disaster, Seelos explained his people's unwillingness to aid the rescue efforts to Captain Jean-Luc Picard. (COMIC: Assimilation²)
