In a conversation with Val-El, Adam Strange makes a satiric take on Marvel Comics Doctor Strange. Val-El calls Adam "Mr. Strange" to which Adam replied "Mr. Strange was my dad. ... Call me Doctor. No, better make it Adam."
When Adam Strange is addressed as "Mr. Strange", he says, "Call me Doctor. No, better make it Adam". In the comics, Adam Strange is often referred to as a doctor, as he has an academic degree in archaeology. However, he's only known as Adam to distinguish himself from Marvel Comics' Doctor Strange.
