Dredgen Yor- A maelstrom of dark magic. Yet the dark deal he made certainly holds him to the logic of the blade. A weakness. Would anyone understand this enough to beat him like Shin Malphur did? Jaren Ward- A Hunter (or rather, a pre-Hunter, Ranger) now dead, that was once legendary. Would lose to the twisted Rose that once beat him before. Right? Kabr- A Titan who dove headlong into forces barely understood. While he chose sacrifice for the greater good, would anyone be able to best hin in a rumble? Maybe the one who inspired him to seek the Vault. Osiris. Wei Ning- A tireless Titan who had a fist almost as feared as Saint-14's headbutt. Eventually died from the mistake of taking on Crota's Legions. Most likely would be defeated by the hive magic of Thorn. An independent Titan who don't need no man, regardless Toland- An obssessive old man with deep knowledge of science, able to manipulate it into what the weak minded might call "magic." One of the top 3 contenders, even more if you include that he is a Sunsinger who understands how death works to a degree higher than even the Thanonauts. Osiris- A man labeled a blasphemous for asking "why?" Found revelation after revelation into the true nature of the Darkness. Exiled, but a great fighter in the City's struggles. He was "everywhere at once [on the battlefield]" and has since been into the pattern obsessed Vex. He has witnessed the patterns of battle and history, and can now utilize them for humanity's saftey. Understanding the patterns should allow him to defeat Dredgen Yor- and the deeper capabilities of Osiris and Warlocks in general would insure victory. Osiris wins.

Wei Ning no contest on this list.

Osiris is very underrated. He could possibly be able to manipulate time with his knowledge of the vex. We certainly do not know what he is capable of.
