Yes, these looks are based on Heathers.

Logic: Y'know, she's logic,tells me what the most logical reason I screwed up or something. She's got a short temper and if she forgets something, she improvises.

Knowledge: Ah yes, she stores all the information I've ever learned and stuff. She's calm and likes to spout random facts when she's excited.

Reason: Reason is making a choice based on our own ideas or self, sort of the opposite of Logic. She's bubbly and gets along great with Morality. She likes dad jokes, although she does cringe at the worst ones.

Morality: Moral compass, sort of like Reason. The two have similar personalities and Morality has my sense of love for animals, except for bees, spiders and ants (and wasps). She can get confused by the other traits because they can influence her easily :p

I have no names for them yet! You can suggest names if you'd like.
