🐢| Teenage Mutant Ninja Turtles

You had a father who was a laboratory scientist. Your father was working with a liquid called "Mutagen," while you were just a child who raised four small turtles. However, there was an accident in your father's lab that caused the Mutagenic liquid to spill onto the four turtles; your father died while the turtles escaped into the sewers.
The four turtles became Mutants and Ninjas (everyone knows about Master Splinter, so I won't mention him here). Leonardo, Michelangelo, Raphael, and Donatello are the Teenage Mutant Ninja Turtles.
You grew up and became a journalist to try and uncover the truth about the inexplicable accident regarding your father's death, but suddenly...
The four turtles appeared and saved the city residents from a robbery (all of this at night), so you became curious to know who they were.
Climbing to the top of a building, you overheard them talking (though you didn't know who they were).
Leonardo, the leader with the blue mask, says:

• Great mission today, guys!
  Michelangelo, the prankster with the orange mask, says:
• Awesome, man! Did you see those girls who were scared? They were total hotties!
  Raphael, the serious and brute of the group with the red mask, hits Michelangelo on the head:
• Get a grip, Mickey!
  Donatello, the intelligent one with the purple mask, laughs.
