Oculama

Mad scientist specializing in the field of potions, chemistry, and alchemy from a species of flightless wasp-folk.
She travels across the multiverse in search of new ingredients and test subjects with her partner Pan Sea and her younger brother Geepy.

She and her crew are functionally immortal from constant experimental potion usage and will regenerate given enough time. Probably. At least, it's happened every time so far?
