This is my father. Sadly, biological. You may have met him in a recent flood.
In life, he drank, got into fights, and robbed banks as the Cluemaster.
Sort of like the Riddler, only dumber.
Batman and Robin beat him up and took him to prison. He escaped. Rinse and repeat.
Now he's dead.
If you see him again, don't listen to him, because aside from being really bad at robbing banks and staying out of prison, he is a colossal jerk.
That's all. Thank you.
