ah yes. memories
my oldest characters that i still use (including poor chris) were made as mlp oc's. when mlp:fim was still popular i went through an 4 year long mlp phase and i wanted some pony oc's,,,,, i made my own mane 6 and everything :"0 eventually after i made human versions of them they became their own characters and i gave them their own story once i grew out of this  f o u r  y e a r  l o n g  phase. chris and peter in particular were also inspired by fred and george from harry potter (i made one troublemaker instead of two b/c i was afraid of copying them) and jacksgap (some british youtubers i used to watch at the time, this was before they changed their videos).
they've come such a long way,,,
