Albus Dumbledore:

Headmaster and Hogwarts

Harry Potter has always had his support

He has a keen eye for things unseen

To Harry, Ron, and Hermione, he could never be mean

He fled from Umbridge's grasp

Causing the Ministry to gasp

There is always something up his sleeve

That you can only discover if you truly believe

Draco Malfoy couldn't kill him

And just when things for the young Malfoy were looking grim

Severus Snape stepped in

Though he wasn't really gone

In Harry's heart, he lived on

Though he is rumored to be gay

That stereotype he doesn't portray

Keeping Harry safe is never a bore

He is Albus Dumbledore
