This is more of a conspiracy theory than anything.
Lord Shaxx. Titan. Crucible Handler. One of the Heroes of Six Fronts. But…is he really who we think he is?
I think Lord Shaxx is an evil Hive god, pretending to be a guardian, who snuck into our ranks. He chose the most “warbeasty” class, the Titans, he always wears a mask, and he literally is in charge of Guardian fighting. Sounds like the perfect spy/scheme. He could easily sneak in the Tower’s main halls and kill the important people easily. And since he is immortal with a throne world, he can resurrect himself. Watch out Guardians, Shaxx is coming.
