Thanos is one of the strongest villains in the Marvel Universe and has fought with many heroes like Avengers, The Guardians of the Galaxy, etc. He is often regarded as the one who seeks balance. He has 2 adopted daughters, Nebula and Gamora. Thanos, the Mad Titan had a secret son in the Comics, who is named Thane. This secret son of Thanos wanted to kill his dad, just like Nebula (the adoptive daughter of Thanos).
The Infinity Crossover series
When Thanos’ Black Order on Earth-In the Infinity Crossover series (2013), each member of his loyal team did every task by heart and they all lived up to their chief’s legacy. Thanos told the heroes that if they do not want destruction, they need to pay a tribute in return. The Tribute was that he wanted the heroes to bring the heads of all Inhumans between 16-22 years of age. It clearly shows that Thanos wanted to find his secret son Thane, who was hiding on the earth and was partly Inhuman. So, his actual motive was understood but why he wanted to do that to his secret son was because Thane wanted to kill his father, Thanos out of revenge.
Thane trapped Thanos in a chamber
After a religious search, it was found that Thane was hidden in the secret Inhuman City of Orollan. He had not been transformed into Inhuman as the city had a single piece of Terrigen Crystal only. This means that Thane’s Inhuman transformation would only happen once in a generation. However, what is more, important to know is that, Thane was a good guy and a healer who enjoyed separation. But Thane transformed into a monster when the Terrigen Mist bomb was exploded by Black Bolt due to a fight with Thanos. And so, He killed all Orollans during his Terrigenesis. However, he was later captured by Thanos and the Black order but was released by Ebony Maw. “You have a decision to make, boy. Will you reach out and take what is yours?” Said Maw to Thane. And he proceeded to trap his father, Thanos in the chamber- “Living Death”
If Thane wouldn’t have encased his father in the “Living Death” chamber. Thane would’ve reappeared in the Thanos (2017) written by Jeff Lemire, Mike Deodato, German Peralta, and Rachelle Rosenberg. Thanos met his son for the last time after acquiring the power from the God Quarry and he managed to separate the Phoenix force from Thane and threw him into the quarry.
Defeating Thanos was out of the question until his Son, Thane did it. Thane not only trapped his father but left him in the LIVING DEATH chamber. While Thanos was no doubt, the BADDASS and he could have escaped. Thane proved that he was a better successor and deserved it all.
