Diegoniisan Gameboy

Super-teen extraordinaire
Freakazoid! Freakazoid!
Runs around in underwear
Freakazoid! Freakazoid!

Rescues Washington D.C.
Freakazoid! Freakazoid!
Unless something better's on TV
Freakazoid! Freakazoid!

His brain's overloading
It has a chocolate coating
Textbook case for Sigmund Freud
Freakazoid! Freakazoid!

Check out Dexter Douglas
Nerd computer ace
Went surfing on the internet
And was zapped to cyberspace
He turned into the Freakazoid
He's strong and super-quick
He drives the villains crazy
'Cause he's a lunatic

His home base is the Freakalair
Freakazoid! Fricassee!
Floyd the Barber cuts his hair
Freakazoid! Chimpanzee!
Rides around in the Freakmobile
Freakazoid! Freakazoo!
Hopes to make a movie deal
Freaka me! Freaka you!

He's here to save the nation
So stay tuned to this station
If not, we'll be unemployed
Freakazoid! Freakazoid!
Freakazoid!!!
