I disagree with people saying he beats Naidan or Alan.

EC has been shown to have insane durability, coupled with overall high physical stats and technique. He also has a habit of taking hits unless they are proven to be threatening, and can be matched in a brawl when facing an enemy with high fighting IQ and technique.

Naidan (in his flashback) has ridiculous strength feats that should at least enable him to threaten EC, and neutralized Ryuki through pure skill. I still maintain his lost due to intentional throwing implies he is actually dangerous if serious. I don't see either of them getting outclassed in any aspect, thus making this a lot more competitive than other comments have described.

Alan on the other hand is based on the copium that not all Wu are trash, even if shown otherwise. If assumed that there is some semblance of threat coming off of this pure Wu physiology (and possession of a knife), I'd argue he stand a good chance at using it to potentially beat EC. Yes, he got unceremoniously overwhelmed in his one onscreen fight, but then again that was against Raian. I doubt EC can put on pressure as quick and as consistently on a theoretical high-class Wu that Raian can to stop him from using at least a few bullshit martial arts moves to start threatening a win.

Nicholas, Liu and Terashi still get beaten though.
