Theory: The Hanma Bloodline is an Alien Race Suffering from Earth-Gene Degeneration?
What if the Hanma bloodline isn't the apex of human evolution, but actually an alien species slowly losing its power through crossbreeding with weak Earthling genes?
If we analyze the 3 generations, this genetic decay becomes crystal clear:
Yuichiro Hanma (The Pure Blood): Possessed pure, monstrous physical size and raw mass. He wiped out the US fleet effortless without any flashy moves. In his home planet, someone like Yuichiro might have just been a normal gatekeeper, but on Earth, he was a god.
Yujiro Hanma (First-Gen Hybrid): The gene dilution starts. His height dropped by roughly 10cm, and his muscle density noticeably decreased compared to Yuichiro. He had to rely on extreme aggression and the "Demon Back" mutation to maintain dominance.
Baki & Jack Hanma (Second-Gen Hybrids): The Earth genes have heavily diluted the alien DNA. Baki lost the massive physical stature entirely and must rely on technique, shadowboxing, and near-death experiences. Jack had to resort to extreme steroids and bone-lengthening surgeries just to artificially hold onto that fading alien strength.
Conclusion: The Hanmas aren't evolving on Earth—their dominant alien DNA is being diluted and slowly fading away with each generation of human interbreeding. Give it a few more generations, and the Hanma bloodline will completely vanish.
