Predator can change how he looks but... he really prefers not to leave a large paper trail like that. Changing identities leaves way too much that can be tracked. So connecting Predator to Exekiel Law is something he will strongly avoid. STRIKE and the Shroud Syndicate should have no real reason to have his real identity or even too much about Predator in general yet since he's relatively new and overshadowed by the more public actions of both heroes and villains.
