Ariel Diaz is a self-taught freelance illustrator and cover artist based in Wylie, Texas, and one of the most prolific and convention-active cover artists working across the full spectrum of mainstream and independent comics today. Fully devoted to her art career since 2013, Ariel has built an extraordinary client list spanning DC Comics, Marvel Comics, BOOM! Studios, Dynamite Entertainment, IDW Publishing, Image Comics, Action Lab, Heavy Metal, Absolute Comics, UDON, and Dark Horse — a roster that places her among the most widely published cover artists of her generation.

Her credits span some of the most recognizable titles in comics — cover work on Absolute Batman, She-Hulk, Amazing Spider-Man, Hallows' Eve, Something Is Killing The Children, The Boys, Witchblade, G.I. Joe, Vampirella, Red Sonja, Taarna, White Widow, and Zombie Tramp, with her most recent credit being a SweetDeevs / Captured Collectibles SDCC 2026 exclusive variant for The Smart Division #1 (Dark Horse Comics) — the same retailer partnership that brought her to NiFe WARS. A fixture on the major convention circuit across Texas and nationally — from MegaCon to Fan Expo Dallas to L.A. Comic Con — Ariel brings the same energy and warmth to artist alley that she brings to every cover she creates.

Her four Captured Collectibles retailer exclusive variant covers for NiFe WARS Issues #1 and #3 mark one of the franchise's most exciting retailer exclusive partnerships — and bring one of independent comics' most recognizable cover styles to the NiFe WARS universe.
