The bodyguard himself

Ryoko is the Forsaken Quartermaster, and elite bodyguard of Sylvanas. He is considered her right hand (wo)man. In episode 4, he leads an ambush against Jonith and Vincent. Seeing that the two are handling the horde well, he charges into the battle on a skeletal warhorse. Ryoko takes on Vincent with no issues and leaves him for dead. He absorbs Jonith blows with perfection and also defeats the paladin.
