Could it be Dr. Popular? We don’t know him for his name, but we know that he invented gyro flops, branding, Moebius, washing machine, and lots of tricks?
I think he has black hair,
We don’t really know him for his name,
We know his tricks,
He’s not new,
He was definitely sponsored by some of those companies, (I’m sure YYJ Sponsored him)
He’s definitely a guy,
And im 100% sure that he’s not Brandon Jackson
I think its eric koloski because everyone would know some tricks named after him (i.e koloski tower and ping pong koloski), he has black hair, he’s a he, and he’s sponsored by YYJ.
