My Riddled Wish

I'm gonna let you figure this out

I am a puzzler riddled with pain
What in life do I hunt in vain
Try to decipher my little twist
Find the heart of this riddled wish
Riddle me this riddle me that
Here's the teaser I want you crack
A winged rat the feisty feline
What is shared besides capers and crime
What is free with complexity
The greatest of all mysteries
A blissful enigma of uncertainty
 Hooray at least you've reached the end
What do I want to have and defend?
