IRON MAN GLOW-IN-THE-DARK T-SHIRT -Tony Stark Reactor T-Shirt

Here is an example of how the T-Shirt seen above actually glows in real life.

Anthony 'Tony' Stark was born on Long Island, New York, the son of Howard Stark, a wealthy industrialist and head of Stark Industries, and Maria Stark. Tony is a boy genius, entering MIT at the age of 15, and graduating at the top of his class. After his parents' accidental deaths in a car crash, he inherits his father's company.
While observing the effects of his experimental technologies on the American war effort, Stark is injured by a booby trap and captured by the enemy, who then orders him to design weapons for them. However, Stark's injuries are dire and shrapnel in his chest threatens to pierce his heart. His fellow prisoner, Yin Sen, helps Stark use the workshop to secretly design and construct a suit of powered armor that saves Stark's life by keeping his heart beating. Stark uses the armor to escape, although Yin Sen dies during the attempt. Stark takes revenge on his kidnappers, then heads back to rejoin the American forces. Along the way he meets a wounded American Air Force helicopter pilot, James "Rhodey" Rhodes.
Back home, Stark discovers the shrapnel lodged in his chest cannot be removed without killing him, and he is forced to wear the armor's chestplate beneath his clothes to act as a regulator for his heart. He must also recharge the chestplate every day or else risk the shrapnel killing him. The cover for Iron Man is that he is Stark's bodyguard and corporate mascot. To that end, Iron Man fights threats to his company, Communist opponents such as the Black Widow, the Crimson Dynamo and the Titanium Man as well as independent villains like the Mandarin. No one suspects Stark of being Iron Man as he cultivates an image as a rich playboy and industrialist. Two notable members of Stark's supporting cast at this point are his personal chauffeur Harold "Happy" Hogan and secretary Virginia "Pepper" Potts, to both of whom he eventually reveals his dual identity. Meanwhile, Jim Rhodes would find his own niche as Stark's personal pilot of extraordinary skill and daring.
The comic took an anti-Communist stance in its early years, which was softened as opposition rose to the Vietnam War[3][8]. This change evolved in a series of stories with Stark profoundly reconsidering his political opinions and the morality of manufacturing weapons for the military. Stark, however, often shows himself to be occasionally arrogant and willing to let the ends justify the means.[citation needed] This leads to personal conflicts with the people around him, both in his civilian and superhero identities. Stark uses his personal fortune to not only outfit his own armor but to develop weapons for S.H.I.E.L.D. and other technologies such as the Quinjets used by the Avengers, and the image inducers used by the X-Men.
