Doomsday (Also known as 'D.D') is a "miniature" indominus rex owned collectively by Tacy, Genny and their friends. She's generally well mannered, but is no stranger to biting people.
She's an ancient OC of mine I created shortly after watching Jurassic world for the first time as a kid. More specifically, she is the result of me hearing one of the characters talk about creating a smaller indominus rex and deciding to create my own take on it since I loved (and still love) the indominus rex. She used to be an imaginary friend, but eventually became a normal OC with time.
