Batman carries a well-deserved reputation for burning through sidekicks faster than Batmobile tires, and while Dick Grayson remains the most famous Robin, numerous others have held that title. Following Grayson, Jason Todd and Tim Drake in mainline DC continuity is Damian Wayne, Batman's biological son.
Damian Wayne is the son of Batman and Talia al Ghul. This makes him an heir to the world's greatest crime-fighter, and its greatest super-villain Ra's al Ghul. Damian became the fifth Robin, working alongside his father as Batman.
Morrison brought back the idea of a son, Damian, being born from a love affair between Batman and Talia al Ghul, the daughter of his nemesis, Ra's al Ghul. The boy had been trained from birth by the League of Assassins and was sent by Talia to live with Batman in a plot to disrupt his crime-fighting and distract him.
In current continuity as of 2021, Dick Grayson serves as Nightwing, Jason Todd is the Red Hood, Stephanie Brown is Batgirl, and Tim Drake has picked up the mantle of Robin again after a stint as Red Robin. Damian has left behind the title Robin, but remains the title character of the Robin comic book.

He became Nightwing and eventually was replaced as Robin by a new orphan. Despite this, however, Dick was actually officially adopted as Bruce Wayne's son—multiple times in multiple stories, even!
That series is ultimately a love story between Bruce Wayne and Selina Kyle, as well as one that asks whether Bruce can ever truly be happy and still be Batman. That comic made headlines in 2017 when Bruce proposed to Selina in Batman #24.
One of the mysteries in director Todd Phillips' Joker is whether Arthur Fleck really is the son of Thomas Wayne as his mother Penny Fleck claimed. Both Wayne himself and Alfred Pennyworth said it was untrue and that Penny was delusional, hence her eventual stay in Arkham Asylum.
It also proved that no hero is truly safe from the plot in this universe. Batman disowns Damian Wayne as Superman recruits him to join the One Earth Regime. After Nightwing's death, a part of Batman never truly heals. The loss of Batman's adopted son validates that Superman's One Earth Regime must end.
Also, much like most of the other Robins, Carrie eventually graduates into a more adult role, becoming Catgirl in Miller's follow up series, BATMAN: THE DARK KNIGHT STRIKES AGAIN. Tim Drake was the third Robin within official DC Universe continuity, adopting the mantle after the death of Jason Todd.
Jarro grew attached to Batman and even often calls him “father”. He wanted to prove to Batman that he can be the best Robin and even convinced Batman to give him a chance. Jarro became the new Robin and was even said to be Batman's favorite Robin, admitted by Batman himself.
Everyone knows Robin is Batman's son, but this moment from Action Comics introduces a bat-shaped paternity bomb via a Metropolis local. In DC Comics, Damian Wayne has held the title of Robin for some years now, and it's a matter of canon that he is the biological child of Batman and his former lover Talia al Ghul.
Dick Grayson is the adopted son of Bruce Wayne, better known as the vigilante Batman. Trained by the Dark Knight himself, Grayson eventually became Batman's sidekick, the first Robin.
As we come to learn, not only was Penny a Wayne employee, but she claims she and Thomas were lovers and that he is Arthur's father. That's right: Batman and Joker are half-brothers, at least according to Penny.
Among the big announcements from James Gunn about the future of the DCU was news of a new Batman in a film called The Brave and the Bold. This movie would have our first big-screen Robin in 25 years. But that Robin won't be Dick Grayson, but Damian Wayne, Bruce's biological son.
Superman is without a doubt one of the most powerful heroes in the DC Universe and one of the most difficult heroes to fight, but one dark future version of Robin is surprisingly the ultimate Superman killer.
The Dark Knight is considered by many to be one of DC Comics' best fighters, but Bruce's old partner Nightwing is no pushover, and he even beat Batman in a one-on-one fight.
