Another Marvel Legends 80th Anniversary Vintage Carded figure has been listed on Amazon in Mexico. This Gray Hulk uses the same sculpt as the SDCC 2019 version, and also comes with ripped shirt and the crushed pipe accessory.
This is Hulk as he was first imagined by Stan Lee and Jack Kirby with gray skin. Due to printing issues the gray turned to green and this change was soon made permanent. The Gray Hulk was then explained as an alternative inner Hulk personality with the Green Hulk being a different persona and more savage.
It is unclear as to when this will release, but we assume late 2019 as with the other 80th Anniversary single figures like Agent Anti-Venom and Logan
"Accidentally exposed to gamma radiation, scientist Bruce Banner gains super strength, stamina and invulnerability.... at the cost of his genius. Dubbed "Hulk", Banner at first only transforms at night before realizing that it's actually his anger that gives him his super abilities."
