"The faster they undergo change, the more violent the explosion."

That's Walter White, a.k.a. Mr. White, talking. He's lecturing a semi-bored-looking room full of students in his day job as a high school chemistry teacher. Explaining some sort of chemical reaction. But he may as well be writing his own autobiography.

In the past five seasons of Breaking Bad, audiences have witnessed the extreme evolution of the character of Walter White from doting husband and father to ruthless drug kingpin. His transformation has not been a slow or subtle one; in the pilot episode alone we see glimpses of the man who will become known as Heisenberg, the steely-eyed, fedora-wearing emperor of the New Mexico meth trade.

And when it comes down to Walter versus the world, he'll stop at nothing to win. Witness The Evolution of Walter White, in GIFs.
