The origin of hydra
Hydra, now people think it originated from Nazi hydra, but it is not. Nazi hydra is only a branch of hydra in the long river of history, and it is not an orthodox hydra. Nazi Hydra was founded by Red Skull following the concept of Hydra in previous dynasties, not an orthodox Hydra.
The orthodox hydra organization coexists with all historical branches and silently subsidizes the development of each branch. The origin of the orthodox hydra organization is quite early. About 1400 years ago, a powerful alien hive appeared on the earth at that time, and aliens were sent to a distant planet because of their strong ability.
