seen before—a thinking, calculating, brutal weapon-toting kind of Hulk." To further distance the character away from the original: "Everything the Green Hulk isn't, the Red Hulk is. Except, of course, for his powers which are identical. And he looks the same, except he's red. And he's the same size. But other than that, they're complete opposites." The character has abilities almost identical to those of the Hulk. The character can also emit heat at will from his eyes during non-enraged periods and can augment power levels by absorbing various types of energy, such as gamma radiation (in one instance causing the Hulk to revert to alter ego Bruce Banner) and the Power Cosmic. When infected with Cable's techno-organic virus during the "X-Sanction" storyline, he was able to control this heat to burn the virus out of his system. Red Hulk was created through a combination of gamma radiation and cosmic rays. The satellites used to revert the Hulk to human form at the end of World War Hulk were used to power the device used to turn Ross into the Red Hulk. Unlike the green Hulk, the Red Hulk does not revert to human form when rendered unconscious, and his blood is a fluorescent yellow instead of green, remaining that color even in human form. Unlike the green Hulk, who gets stronger as his rage increases, Red Hulk's body temperature rises with his anger. Though the heat is intense enough to melt desert sand into glass, it causes him to weaken when it becomes too intense, as his physiology lacks a cooling mechanism to deal with the excess heat. Red Hulk has also been shown to have a weakness to Negative Zone energy, which caused him burning pain and drained him when he attempted to absorb it.

The first five issues of the 2008 Hulk title sold out, and second printings featured new covers. Issue #6 was the second-best-selling title of September 2008, and issue #10 was sixth in February 2009. Augie De Blieck Jr. of CBR.com gave the first six issues a positive review, describing it as a "silly fun action romp" and a "popcorn comic". De Blieck liked Loeb's lack of subtlety when giving out clues, saying "this
