I have a lizard names Lagini
Oh a Lizard is an interesting animal. The Lizard is also a character in Marvel's comics.
Really. Which Comic book is that. I will love to have a look
It is typically a villain in Spider-Man. 
Okay. But i know a lot of spider man comics but I never see a lizard as a villain and i do not want it to be one because i love lizards 
Well, it is based on a guy, Dr. Connors who was a biologist who researched reptiles. He turned himself into this Lizard man hybrid.
