Seriously badass porcupine

Underdog was an impressive superhero. He spoke in rhyme. He saved Sweet Polly Purebred every week. He was not bothered by collateral damage. He even had a great catchphrase:

There's no need to fear--
Underdog is here!

But when I think of underdogs in the future, I’ll be thinking of a porcupine.

This porcupine. The one that survived an encounter with 19 lions.
