Blastrhas a story about a guy who is suing the BBC claiming that he created Davros, the creator of the Daleks when he was 13 back in 1972.
Honestly, I don't even care if this is true. If you waited 39 years to sue, you gave up the right to bitch 39 years ago. Doctor Who is not an obscure series, and you should have known that this happened. Get over it.
When I was a kid, I created a character named Nightwing, who was a superhero that looked a lot like the Nightwing that DC comic eventually released, should I sue them? Even if I had a reason to believe that they knew about my drawing, I lost my right to sue decades ago.
If this is true, give the guy credit, and get on with life. He lost his right to money a long time ago.
