Miles underground, the fiercest villains paced the small room. And the door opened. Slade entered.

He began to speak.

"Our mortal enemies are out there. We will not cease havoc on Jump City until those blasted teenagers are gone. WE WILL SEEK REVENGE!" and he stood down.

And so answers the question of why the Villains always haunt Jump city, and why Slade is the worst. He has the largest grudge on the Titans, and hates Starfire and Robin the most.

This was not the end of Slade. Oh no, this was the beginning.

What he did not know was that Teen Titans was formed. And their alliance would never break.

Long Live the Teen Titans.
