Well, without having read it, the 'pantera graphic novel' could potentially center around a panther - like character named Pantera. It could be set in a fantasy realm where Pantera has to face different challenges, like battling dark forces or going on a quest to save their homeland. It might also include a rich tapestry of supporting characters and sub - plots that all contribute to an overarching story arc.
I'm not extremely familiar with the 'Pantera Vulgar Display of Power Graphic Novel' specifically. It might be a graphic novel inspired by the Pantera album 'Vulgar Display of Power'. It could potentially feature the intense and aggressive themes that the album is known for, perhaps translated into a visual story with characters and art styles that match the raw energy of Pantera's music.
In this fanfiction, Naruto might initially struggle to control Pantera's power. Since he's used to his own chakra-based abilities in his own world. But as he gets to know more about Pantera in the DxD setting, he could start to master it. He might team up with some of the characters from DxD, like Issei, and they could go on adventures together, using Naruto's new - found power of Pantera to defeat common enemies.
If Broly participated in the Tournament of Power, he would be an absolute powerhouse. His raw strength and uncontrollable rage could either make him a wild card that disrupts the whole tournament or a key player for his team. He might start by randomly attacking opponents without much strategy, but as the fight goes on, his natural fighting instincts could kick in and he could become a real threat to the strongest fighters in the multiverse.
Bulma could be another character paired with the reborn Broly. She might be the one to help him understand the modern world if he is reborn in a different time period. She could use her intelligence to create devices that help Broly control his power better or she could just be there to provide some comic relief in the midst of all the intense Saiyan drama.
