Gemini (May 21 – June 20) – Iron Man/Tony Stark
Tony Stark is one of the few Avengers with a disclosed on-screen birthday. Since he was born on May 29, he’s a Gemini. Though Geminis still have an unwarranted reputation of being chaotic with their personal relationships, they are actually one of the most selfless signs.
There are other famously selfless signs, such as Pisces, Virgo, and Aquarius; however, Geminis are some of the more exorbitantly selfless members of the astrology kingdom. They extend their altruism to their friends and loved ones first, but they would willingly neglect their mental and physical health if there was a slight gamble that they could make a community, the world, or the universe a better place.
Perpetuating intergalactic prosperity is a subjective concept because making anything better can take on different forms. From Tony risking his life on numerous occasions to creating a home for all the Avengers, including Steve even though they still haven’t made amends, his selfless CV is lengthy, to say the least. Sure, Steve might be the selfless, star-spangled shield-slinger, but Tony is the generous heart of the Avengers who only hides behind his egotistical facade.
He might parade as a selfish billionaire playboy philanthropist, but Tony puts his life at risk in every one of his appearances just for the prospect of helping others. Because he has an innate duality in their sign, this could explain the surface level personality Tony bares to unfamiliar acquaintances versus his real, self-effacing intentions.
However, Tony’s canon duality likely lies in the emotions he expresses and the true emotions he often conceals. After all, he uses his selfless acts to cope with his childhood-turned-lifetime anxiety and his unresolved PTSD after being kidnapped, tortured, and enduring the infamous alien invasion.
