The first I can remember was Zordon in Power Rangers in Space, followed quickly after by Kendrix in Lost Galaxy. A bit later but also ones that stick out in my mind are Joyce from Buffy the Vampire Slayer and Pyrrha from RWBY.
I know it said “First” but I can never only pick on thing.
fuck it, i'm curious. reblog and tag with the first fictional death to ever rewrite your brain chemistry and/or make you cry like a baby. mine was ares from the underland chronicles (who, for context, was a giant bat.) to this day i will weep if i think too hard about it. okay, go.
