Saint and Sinner, a Christian superhero, Saint who unwittingly changes into her villainous alter ego, the tall scythe wielding Sinner at times of stress and vice versa. Neither of the two are aware of each other though they hunt one another.
Shadowraith would first find a way to tell which are the real monsters or those wearing PJ Masks costumes before trying to save anyone. (As well as snatching a goody bag or two that won't be missed.)
When in doubt, steal your gear from supervillains. For example someone who takes the devices of deceased villains like those 17 guys killed off by Scourge in the Bar with No Name in Ohio and incorporates them for his own use or who finds one of Norman Osborn's hidden goblin lairs and swipes a goblin glider.
Shadowraith orders a Hawaiian pizza then investigate the manager. A ghost out for revenge is odd considering how it took said ghost so long to act and why would it even use a robotic mascot to do so? Did Foxy use abacuses instead of electronic cash registers this entire time?
