But in fact looks more like Giganto Jr. According to spotlight he teams up with moleman for sp1 but sp3 is entirely Giganto Jr himself and if you look at the image dave posted on twitter he sorta looks like him...Bare in mind the image doesnt show the final product of the champion as clearly he still being polished and getting final touch ups for next week update.
