The Dark Mantis Returns?

From Fringe this week;

Fauxlivia: You thought this might have something to do with the vigilante case the PD has been working?

Agent Lee 1: Maybe Batman’s moved to the Bronx

Fauxlivia: What’s a Batman?

Agent Lee 1: The Caped Crusader and the Dark Knight… billionaire playboy puts on a cape to clean up the the streets of Gotham?

Agent Lee 2:You mean Mantis

Agent Lee 1:Seriously? Your superhero is an insect?

Fauxlivia: Because nothing says bad ass like a flying rat.

Looks like in the Fringe Alternate Universe, they took the Death Of Batman a lot harder than the death of Superman…
