Mattis Banz was a Force-sensitive human male who was a member of J-Squadron, a training group within the Resistance against the First Order. Born on the farming planet of Durkteel in 20 ABY, Banz grew up as an orphan, residing under the care of a Phirmist temple, where he heard tales of the Rebellion that overthrew the Galactic Empire. During this time, he developed a heroic personality, dreaming of becoming like Luke Skywalker, Leia Organa, or Admiral Gial Ackbar, and he often helped younger orphans in need.
