Opening theme song.
It started when an alien device did what it did And bonded itself upon his wrist with secrets that it hid
Now he's got super powers He's no ordinary quirkless kid
He's Izuku 10!
(Izuku 10!)
So if you see him you might be in for a cosmic surprise He'll turn into an alien before your very eyes
He's crazy, creepy, fast, and strong He's every shape and size in the omniverse
He's Izuku 10
(Izuku 10!)
With all powers he's on the case Fighting off evil from Earth or space
He'll never stop till he makes them pay 'Cause he's the baddest kid to ever save the day
Izuku 10!
