If you're a fan of Drax, you'll want to know about Kronos. Kronos was a scientist who messed around with cosmic energy and paid the price for it. After Drax and his family were killed in the Mojave Desert, Kronos found his energy (I guess when you're a cosmic being you just come across people's energy?) and he made Drax into a super-warrior to stop Thanos. You can see where the inspiration for the movie Drax came from, but it is still very different. I don't remember the 'Guardians of the Galaxy' Drax being from the Mojave Desert.
Kronos was defeated by Silver Surfer and the Hulk on different occasions, but since he can reconstruct himself over time, he'll be back. I wish I could reconstruct myself. Sometimes that's what I feel like I'm doing after a five hour nap.
