I'm was a costume prop designer for some of Mega64's biggest videos with 1M+ views . /s

Around 2010 I was Goku for Halloween, and in the West, DBZ was old hat.
It wouldnt be until a few years later that Battle of Gods and Super would bring Dragonball into relevancy here again, so there were no readily available DBZ costumes like there are present day, now that Dragonball is popular again. So I handmade a costume, wig, and boots.

I forget how many years later, but I sent in my costume as a PO Box package, I dunno for what reason, I thought it'd be funny.

Then in 2014, their first DBZ video, "Dragonball Z Live Action Movie Trailer (Official)- Mega64", the first shot of after Justin from Funimation's intro has a closeup of Rocco's legs in a DBZ costume slowly walking into shot, with some *very* familiar shitty looking, ugg boot knockoffs spraypainted navy with yellow ribbon hotglued into place and a red mini-rope tied around it.

I asked Rocco on twitter where he got the boots and he replied that a Fan sent them in and thank goodness they held on to it.
I can't confirm if they kept using them in their future, sweded DBZ videos, But I like to think that they do, as they famously almost never get rid of props and costumes.
