Well we're working off canon characters so yeah it is sad. But there was an Iron Lad, who was the young Krang the Conquerer who travelled back in time to stop him with a highly advanced Iron Man suit made of a sort of T-1000 type metal thing.
If I do remake Young Avengers, I think I have an idea that would use Iron Lad's whole set up and keep him around. Since in Young Avengers he left at the end of the first arc... not spoiling the why and such.
