Cavalier

From his first appearance:

"A portrait frowns...a man gasps a last message...and Rance Raleigh casts aside his modest identity to become the Cavalier!"

Powers and Abilities
Other than the supernatural inspiration provided by the portrait animating, the Cavalier has no powers other than superlative swordsmanship, acrobatics and derring-do.
