The সেকেন্ড Robin is Jason Todd and he died a few years after becoming Robin. My guess is about 2014 because if it was any earlier the first Robin, Dick Grayson, wouldn't have been able to create the শিরোনাম Nightwing.
I'm going to guess আপনি don't read comics, do you? Here's how it is in Young Justice. First Robin: Dick Grayson and is now Nightwing সেকেন্ড Robin- Jason Todd, is now dead Third Robin- Tim Drake, is still currently Robin
Jason must have become Robin and died within the five বছর time skip.
Just so আপনি don't get confused if আপনি here something different: In the actually DC comics Jason came back to life and is not quite evil but not good either, Tim moved on from being Robin to being independent (like Dick) and is going দ্বারা Red Robin, and Damian Wayne is Robin.
The সেকেন্ড Robin is Jason and he died after the Joker beat him with a crowbar and blew him up.... There was actually a phone মতামত and the অনুরাগী voted to kill him off. He came bake to life later because of superman... অথবা the lazerus pit অথবা somethin like that :/ then he became the red ঘোমটা and killed a lot of people and eventually ব্যাটম্যান had to fight him. So yes, he died, but he's still alive to!XD
Jason was the সেকেন্ড Robin. He died during the 5 বছর break of young justice tv show. We never saw Jason play as Robin in the প্রদর্শনী because Joker killed him before he could come in as Robin in young justice so they had Tim be Robin.
