JON is an emerged fighter, the combination of VONgeta and Jakarot. Using the Potara earrings, Jakarot and VONgeta fuse to gather more slaves throughout the internet and mostly discord. Though, normally mortal fusions last for an hour, their fusion is unique and it can last for as long as they want.
JON is the strongest Potara fusion. Their superhuman ape strength and predatory nature merged together is a deadly combination
JON is rather a stronger fusion than Vack (VON & Jack), JON is a product of the Potara earrings and he's much stronger.
Hannah likes both Jack and VON. So they fused together into JON and raw dogged her all night.
