The tale of Ganner Rhysode, a vain arrogance that had so many Jedi astray in the past, demonstrated how far fallen Jedi are willing to go. His story arc was ultimately beneficial. He was an aggressive advocate for Kyp Durron’s theory on using the Force as a weapon to fight barbarism throughout the galaxy with hostile intent.
During the Yuuzhan Vong invasion of Republic space, he would defend his position; but his arrogance proved to be his downfall, and he learned a harsh lesson. He’d later risk his life during a crucial operation against the enemy by single-handedly defending hundreds of Yuuzhan Vong soldiers. Even the Yuuzhan Vong recognized him as a legend within their own civilization after witnessing such an incredible event.
