Fionna Character design

A model student from moon colony, Fionna's is a stoic person and mostly unfazed by anything, don't let her deadpan expression when she absorbed in her weird science experiment fooled you, though. she will have no problem dragging the others (nathan and wendy was her usual 'victim') to run her scientific errand and some weird, mildly dangerous experiment for her.

despite her frosty demeanor, one can find her rare warmth smile when she enjoyed her hot coffee during break time.
