I really enjoyed reading this because it was full of wonderful things. You rhymed in the right spots to give the poem something to grasp onto, and you also made the beat of the poem consistant. My favorite part was:

Pegasus he tamed
And flew into battle
The monster he maimed
And it gave out a rattle...

I liked this part because it showed all the qualities I mentioned at the beginning. I liked your choise of words such as maimed and ire. I think I will have to check out what those two words mean! Great job and keep that pen moving!
