Experiment 625
An alien creation by Jumba, 625 first appears across the films and TV series. He's best known for his obsession with food—particularly sandwiches, which he's genuinely passionate about. On a trip to Earth with Gantu to hunt for sandwich ingredients, he discovered every bakery was out of bread. Depressed by this culinary catastrophe, he ran into Yuna's grandmother, who taught him to make onigiri instead. He took to the skill immediately and became genuinely fond of the rice ball-making process.
That interest didn't stick around permanently, though. By the second series, he'd basically abandoned onigiri and went right back to chasing his sandwich dreams like nothing ever happened. Despite his food fixation, 625 shows genuine consideration for others—he's been known to give gifts to both Dr. Hämsterviel and Gantu. Come the third series, he frequently ends up getting punished by Delia, usually alongside Hämsterviel, which suggests he's found kindred trouble-making spirits in his circle.
