A heaven god Digimon that governs over thunder and the weather, he is both a member and the leader of the Olympus Twelve. He always judges right and wrong on the battlefield, and deals out heaven's vengeance on those who work for evil. His judgements are given out plainly, not in an emotive way at all. It's said that if an unconvinced person can challenge Jupitermon over the judgement and win, then Jupitermon will overturn it, but it's also said that there has yet to be a single person so far who has been able to overturn it.
If he lets the hammers in both his hands exchange fire, he can summon a small thundercloud. This thundercloud will automatically give hell to those judged to be evil and wish to disturb others that are judged to be meditating with his "Mavolto" attack.
His "Punish Judge" carves a hammer-shaped seal into the bodies of those opponents he strikes, at the same time giving out his enforcement of their sentence. When the execution of their punishment is carried out, severely electrified lightning bolts will be brought down, and their penalty will be accomplished.
Jupitermon's greatest special attack is "Wide Plasment", wherein his body becomes supervoltage plasma. Everything around Jupitermon will be dealt heaven's vengeance, and those who touch him become vaporized.
