She and Kuprum spend most of their time pranking highbloods as a source of amusement. She also relies on Kuprum in order to fight her voidrot. Her personality, like Kuprum's, is somewhat based on 4chan culture. However, she is shown to disapprove of Kuprum's obsession with the empire and Trizza Tethis. This may mean she is based on one of the less political boards as Kuprum is, and just 4chan culture in general. Her second bullet point, "whats a shower", seems to support this claim, as 4chan users are stereotyped as messy and often unhygienic.

Folykl seems to find great joy in pranking highbloods due to her dislike of them. She was shown laughing and snickering at the highbloods' expense in Hiveswap Friendsim: Vol. 6 alongside Kuprum, and was proud to announce that it was Kuprum that hacked into the blue bloods' GPSs to lead them to the wrong part of town. When the player suggests that it was time to call the prank off, she dismisses the player's idea as idiotic. Even though she and Kuprum view highbloods as outright enemies, they have yet to inflict actual harm on them.

Even though they have nothing but disdain for highbloods, Folykl doesn't exactly feel any sympathy for the oppressed. This is evident when the player (mistaken for a burgundy) is lamenting about how brutal life on Alternia is as a lowblood, Folykl taunts the player for their apparent incompetence for not being able to keep their lusus and home safe. Kuprum later reveals that he and Folykl views everyone as inferiors to them without any regard to social standing, which might be a reason why she remains apathetic to the lowbloods' predicament.

As mentioned above, Folykl does not appear to pay any attention to personal hygiene. Upon their introduction, the player is quick to note that her appearance is unkempt, her hair is greasy and that she smells quite foul. It is not made clear why she opts not to take a shower, though Kuprum seems to have gotten used to her unsanitary presence.

Folykl is shown to have a less than ideal personality: she frequently insults the player (and probably everyone else) with relish, and gives the player a sudden and unwanted tongue-kiss. When the player is much too confused about the entire situation to do anything, she goes on the drain the player of their energy, leaving the player in a immobile heap on the filthy street. Once that's done with, she sarcastically thanks the player for the bit of energy that would sustain her for the next three minutes.

Due to her condition, Folykl speaks in a mostly sluggish manner, but uses informal speech laced with cuss words. She has no problem with ridiculing anyone and everyone she meets, and appears to enjoy mocking other people just for the sake of doing so.

I'd imagine her sounding very weak, like she's actually about to die. She also sounds younger than she actually is due to her small size.
