In the manga, he battles alone representing Europe, instead of being in a team of at least two members. He defeated the Desert Thunder team single-handedly, even beating two players at once. He is very confident in himself and always stays calm and collected. He likes to ride his horse on his rich estate. Julius always has bodyguards nearby to protect him.
Julius is as bitter and cold as he is in battles because when he grew up, around six years before the Big Bang Bladers Tournament, whenever he won trophies at diverse competitions and looked up to his Father for his words of encouragement, the man always indifferently said that Julius might have won some small competitions but he was not the number 1 yet and therefore it was not worth his time. Right after, his Father always left him to go to work. Nero, Julius's brother in the manga, was always happy for him, but had to sadly watch his brother lose all his emotions and focus only on winning and becoming the best in all aspects. Julius always ended up throwing his trophies to the ground, thus shattering them completely. For him, all those trophies only ever made him upset. Fortunately, after his battle against Gingka in the tournament, in which he lost, his Father recognised his mistakes and came to give his son a hug, which the latter wholeheartedly returned, happy to finally get recognition from the father he deeply respected.
Cross Black Excalibur: His special move is Cross Black Excalibur.

Gravity Quake: When Juluis returns before his bey evolves into Vari Ares, he unleashes a new move called Gravity Quake, where Perseus vibrates, causing the opposing bey to swirl around the stadium, then the vibrations strenghen, and hit the bey twice each time around the stadium, eventually hijacking all it's stamina.
