T-Rex: Time for me to create a SECRET IDENTITY! You know...

T-Rex: ...so that I can better FIGHT CRIME??

Dromiceiomimus: In this scenario, you're fighting crime as T-Rex, and the secret identity is your new CIVILIAN identity?
T-Rex: Yes. I'll be "Tori Boring, non-heroic citizen".
Dromiceiomimus: Because that means everyone will look into your CURRENT T-Rex identity, and your NEW identity would be the only safe one. And at that point you're basically just starting a new life!

Utahraptor: Plus, secret identities don't work anymore!
T-Rex: Sure they do!

Utahraptor: Dude, they haven't worked since FINGERPRINTS, and that's putting aside other biometrics like retina scans and facial recognition. When FACEBOOK is automatically picking you out of pics for FUNSIES, the fantasy of being able to pass yourself off as "Bend I. Steele, astronaut /private investigator" is DEAD.

Narrator: T-REX HAS JUST REALIZED HE WILL GO TO HIS GRAVE THINKING ABOUT HOW KICK-ASS AN IDENTITY "BEND I. STEELE" IS:
T-Rex: whoah
Narrator: AND HOW BECOMING "BEND I. STEELE" WILL NEVER BE FAR FROM HIS THOUGHTS:
T-Rex: no regrets
