I apologize if this is not the correct forum (and I don't know where else I would post this, if there's a better place for this then report my post to be moved) but-
Does anyone know who originally created this character?

You play as it in literally almost all of the platformers you find in the explore tab, so I'm genuinely curious about this. There could also be a slight possibility that nobody knows who created it- I just want some sort of answer.

this project is about 2 years old and it uses the generic platformer cube. So StratfordJames could be a possbility

It's a good question. I've certainly seen it around for a bit - that's not to say it's similar ones reappearing. My guess is StratfordJames or another user who started the trend of platformers (in recent years)
