How does Red Hulk actually catch on fire?

I’m loving Harrison Ford’s Red Hulk - it looks amazing. But with Red Hulk finally getting attention from the MCU, a lot of people are furious as to how he “works.” As ever, your answers can be found in my book “Marvel Anatomy!” I hope you like what you see, and I hope you learn something from the text…

Marvel Anatomy is currently sold-out worldwide, but we’ll have more copies in April. Let me know if you want an autographed copy of this 230-page illustrated tome, and I’ll make sure you’re on the list.

And for those of you who’ve been keeping up with my “Painting Marvel Anatomy” series on YouTube, I’ll be releasing both a Hulk episode and a The Thing (of the Fantastic Four) episode soon. Have you ever wanted to know what The Thing looks like under all those rocks? I have the answer… 😉
