I've only seen the batman trilogy, The Batman, and the kids cartoon with the riddler who had the epic green question mark suit.
I have the comics SOMEWHERE in storage since I'm scared to ruin them when I take them out to read 😭
When did batman acquire fifteen million children
Okay, so...it's not exactly 15 million. It just seems that way. And I only have knowledge of 8 of them.
Dick, Jason, Tim, Damian, Cass, and Duke, and technically Barbara and Steph.
Starting with the Robins.
Dick was the first. The first Robin, the first ward, currently Nightwing. He first appeared in 1940.
Jason Todd came second. The second ward, the second Robin, now Red Hood. He first appeared in 1983.
Tim Drake is known as the self-adopted Robin, and he came third, and is currently operating as Red Robin. He first appeared in 1989.
Stephanie Brown was the fourth, and the only female Robin. (she's often brushed off for this, pisses me off.) She currently operates as Spoiler, and she first appeared in 1992.
Damian Wayne, the fifth and the blood son, as well as the current Robin first officially appeared in 2006, but he appeared in Batman: Son of the Demon as an infant in 1987, despite this not being considered canon for the longest time.
Barbara Gordon operates mostly independently but still associates with them, either as Batgirl or as Oracle. She first appeared in 1966.
Cassandra Cain, operating as Black Bat or Orphan most notably, first appeared in 1999.
Duke Thomas, operating as Signal, first appeared in 2013.
Now this isn't accurate to when they actually took up their mantles, but here's a starting point for you, Bat-Anon!
