I'm not afraid of anything

"I'm not afraid of anything." - The Hulk

 The Hulk is running rampant in New York City with the Warbound (aka. his posse) but he encounters one of the Initiative recruits who has the ability to bring one's greatest fear to life. Initially this recruit is able to stand up against the Hulk but eventually his ability fails as the Hulk's confidence rises (along with his anger levels) until eventually the illusion falls and The Hulk spares the beaten recruit.

Now I know you're thinking ... this is THE HULK so he shouldn't be afraid of anybody or anything! You and I are just a bunch of stick figures compared to him ... but if you've read the much acclaimed Planet Hulk collection you'll realize that the big guy had to go through a lot and suffer great losses so he's declaring his defiance after a long, hard road.

No matter how big you are ... there's always somebody bigger than you! Stand up for yourself and don't be afraid of anything because fear empowers those you're afraid of while courage weakens their hold over you.
