Pons Limbic was a Siniteen male who was nicknamed "Brainiac" for his ability to mentally calculate hyperspace jumps. Shortly before the Battle of Yavin, he spent time in Chalmun's Cantina on the planet Tatooine, sitting with the Arcona Hem Dazon, the Advozse Bom Vimdin, the Defel Arleil Schous and the Stennes Shifter Braconnor Bakiska near the door. While the group sat together, the Jedi Master Obi-Wan Kenobi and the former moisture farmer Luke Skywalker entered the establishment looking for a pilot to take them to the planet Alderaan.
