JJ Edgar was a lion half-blood.
He obtained the White Flame Lion bloodline. After obtaining the bloodline and becoming a Sage, he became a prominent figure in House Lowin. This was a prominent faction inside the Last Blood Bastion.
Edgar chose to overwhelm his opponent right off the bat. He tapped into his bloodline transformation from the start, indicating that he hadn't taken Hansen or the forces behind him lightly.
Edgar was around 20 ft tall in his beastly form. He had a thick and voluminous mane and grayish-blue eyes. It seemed that he didn't need weapons. His beastly jaw could tear apart anything Hansen throws his way. His razor-sharp claws had a peculiar shine to them.
Roar!
The thundering sound of a giant white lion's roar was heard on the battlefield and everyone lost cool. Even the most veteran rankers had goosebumps when they heard this roar. They felt like their souls were stirring while listening to the roar.
