This figure from Figuarts Zero seems to have come out of nowhere depicting Goku in the SSJ3 form surrounded by a golden dragon as he unleashes his Dragon Fist. I dont collected this line, but I’m seriously considering getting this. Release date is in August, 2021 at a cost of 8500 yen.
On a separate note, X-Plus has listed a Golden Frieza release in the same time frame. Really looking forward to this as well and hopefully it’s a different pose than the final form Frieza from a few years ago.
