Comic Book Cats, number 25: Final Crisis: Rage of the Red Lanterns, penciled by Shane Davis, inked by Sandra Hope, written by Geoff Johns, lettered by Rob Leigh and colored by Nei Ruffino, published by DC Comics in December 2008.
I’ve never been fond of the whole “Rainbow Lanterns” thing, but we did get at least one interesting character out of that storyline: Dex-Starr, an Earth-born domestic cat who gained a Red Lantern power ring and became an extremely violent, dangerous entity. Dex-Starr was based on penciler Shane Davis’ own cat Dexter. Geoff Johns has described Dex-Starr as “the most sadistic and malicious of the Red Lanterns.”
Dex-Starr has proven to have appeal outside of comic books, appearing in the Justice League Action and DC Super Hero Girls animated series and the video games LEGO Batman 3 and LEGO DC Super-Villains. Dex-Starr even got his own plush toy, because nothing says “homicidal rage” quite like a cuddly stuffed animal.
