Jammers love music. That's all about them. They are typically attracted to sound and rhythm, finding a form of sincerity in music, however, it doesn't go without saying that each Jammer has their own preference of music. Jammers tend to hoard musical instruments or items that make interesting noises when whacked on the tableside, fiddling with them for hours before putting them in a secret stash somewhere, although not so secret as issues tend to arise when most Jammers share the same place for their stash.

Jammers are usually naive, friendly, and just enjoy music. However, this does not make them easy to kill, as however much time they spend praising music as a concept is how much time they spent preparing to defend themselves to live to hear even more music. Employees have noted that their movement is one of the most proficient out of the others, adding that most tend to perform synchronicity: a technique where they possibly may be timing movement to music or imaginary music.

All jammers also have musical synesthesia, which allows them to visualize sound in shapes, colors, form, and movement. This oddly applies to them physically too, with some pulsing in various colors.
