So the Lion and Russ have had five different draws? Amazing.
More or less. We only really know about the first and fifth.
The first time, Russ gave Jonson a solid blow and they started fighting, perfectly matched, all until Russ realised it was foolish and stopped fighting, Jonson taking the opportunity to repay Russ for the first blow.
The fifth time was on Terra, immediately after Horus' death. Jonson blamed Russ for their late arrival, as Russ had insisted they stop to liberate a planet. He attacked Russ with his sword in blind rage, but Russ made no attempt to defend himself, presumably also distraught over the maiming of the Emperor. At the last moment, Jonson realised what he was doing and shifted his blow. He ended up hospitalising Russ instead of killing him, but he apologised afterwards.
1.Magnus the Red- Thousand Suns - Strong enough to break through the terra psychic defenses. He could have toasted them without lifting a finger.
Curse you, HHCCG background! [FFN]Words do not describe the myriad ways in which you suck.[/FFN]
Seeing as Russ broke Magnus' back in open combat, and all, I thought this one was a no-brainer... oh well, vote as you will.
2.Sanguinius- Blood Angels - Even Horus said he should have been the warmaster.
Ah, but that has to do with leadership and strategic ability, not combat skill. Simply being the Warmaster doesn't mean one is the most powerful in combat, or presumably you would have voted for Horus instead of Magnus.
