Alternate reality
Fi'Ja was an alien male who was stranded on the planet Altamid by Krall.
Along with Zavanko and Hider, he approached a crashed Kelvin pod and tried to attack Montgomery Scott, though they were stopped by Jaylah. (Star Trek Beyond)
Fi'Ja was portrayed by actor Danny Pudi. Concept art of Fi'Ja can be seen at TrekCore.
This character was only named in the source's end credits. The character was referred to as "Reptilicus" by the makeup artists. [1]
The mobile game Star Trek: Fleet Command includes an officer named Tiza, who is the same species as Fi'Ja. The species is called the Mirani.
