Mr. Blue

Mr. Blue is a mysterious figure who operates in the shadows surrounding Bruce Banner and the Hulk, deliberately concealing his true identity and agenda while moving through the volatile world connected to Marvel's green-skinned powerhouse.

Mysterious and deliberately enigmatic, Mr. Blue materialized in the pages of Incredible Hulk in 2003 — a Modern Age creation from writer Bruce Jones whose very name suggests someone who prefers the shadows to the spotlight. Operating in the same volatile orbit as the Hulk, Bruce Banner, and Betty Ross, this shadowy figure carved out a small but intriguing niche in Marvel's green corner of the universe. With appearances spanning into the early 2010s and a footnote in the Official Handbook of the Marvel Universe: Hulk 2004, Mr. Blue is the kind of deliberately cryptic supporting player that makes dedicated Hulk readers lean in a little closer — proof that sometimes the most compelling figures in a superhero's world are the ones who keep their cards closest to their chest.
