365 Poems in 365 Days: More Supervillainary

Beaten by a D-list Hero
Before I committed my crime
I will have a mighty revenge
No prison can hold me
(The judge has just ruled to that effect)

So I will change my name, mask, costume
Join the heroes in the fight against criminals
A member of their team, a loyal comrade
And when at last my identity is revealed
I will tearfully tell of my change of heart

All the time he will watch me
Pry at my secrets, wince at my jokes
Waiting for the betrayal I hint at
The paranoia gnawing away at him
Leaving him a mere shell, and I a heroine

Number 295 is another superhero/villain origin story.
