why is number 1 bald

Because #5 didn't help #1 when he was captured sejak the delightful dorks.And well anda pretty much get the rest.

I wish I knew the whole story, but from what i understand, Numbuh 5 refused to help Numbuh 1 when he was captured sejak the Delightfulls and they used some sort of hair removal device, that would make it bald for good.

The delightful children did it to him.

It's a long story. But it was the Delightful Dorks

mr.boss cut all his hair out it seid in a epesode but didnt tunjuk it

In the episode Operation F.O.U.N.T.A.I.N, The K.N.D go to save leeky Leona Number 4 asked why do they have to save her and Number 5 berkata that the last time that she did not save someone it was bad. So number 4 asked what was it and Number 1 berkata that the dcfdtl( Delightful children from down the lane) made him bald.

The dcfdtl shaved no.1 and made it so his hair didn't grow back
