Ryoga Senba
Ryoga Senba is one of the Four Holy Swords—the oldest of the group, actually. He's a seasoned veteran who's been around the block, and it shows. He leads the second squadron of the Black Knights, which puts him in a pretty significant position within their ranks.
He's known for his larger build, which doesn't really factor into how capable he is as a soldier. The guy's got experience on his side, and in a military organization like the Black Knights, that counts for a lot. Being the eldest member of the Four Holy Swords probably means he's seen things the other three haven't, and there's a good chance younger members respect that about him.
