Justice League Vs The Fatal Five: Everything We Know About The JL Reunion

Joining League regulars like Batman, Superman and Wonder Woman are Mr. Terrific, Green Lantern Jessica Cruz, and Young Justice alumni M'gann M'orzz, aka Ms. Martian.

M’orzz made her debut in the pages Teen Titans #37 in August 2006, as a teen alien who later joins the group. Her alien physiology gives her superhuman strength and speed, telepathy and telekinesis, and the ability to phase through solid objects, among other things.

Jessica Cruz makes her animated Justice League debut a full half-decade after she joined the team in the comics. Cruz joins the League in 2014 during DC’s New 52 re-launch, making her the first female Green Lantern to ever do so. Being brand new to the superhero team dynamic makes Jessica an interesting character to follow, and it has been said that she will be a focal point in the film.

Last but not least, Mr. Terrific finally joins the team after only having cameos with the League in past episodes of Justice League Unlimited. Terrific is the third smartest man on Earth, an Olympic-level athlete, incredibly efficient at martial arts and a master inventor. His “T-Spheres” function as portable computers that can also aid him in combat.
