>>10308110I hate to just copy-paste from a wiki but here is her origin
Koopa's character originates from the /hlgg/ thread of 4chan's /jp/ board, when a member (now referred to as Schizo or Dreamer anon) had a dream about a 6th Hololive EN member named Koopa. The post goes as follows:
"Just woke up, had a rather vivid /hlgg/ related dream so I'm typing it out before I forget about it:
In the dream a 6th member of holoEN was introduced way later than the others. Her name was "Koopa" and she wasn't much to look at: she had like dirty green hair that reached just past her shoulders and wore very basic almost colorless clothes and she looked constantly very nervous and shy. I was told by my irl boss to support her for some reason, and I had to do that on /hlgg/ where everyone was shitting on her for being boring and never saying anything. I reluctantly had to defend her but I didn't have my keyboard so I had to say all my posts into a telephone that ringed even though I was already talking into it. Any dream specialists here who could tell me what the fuck any of that meant?"
