HYDRA and the Chitauri scepter
The Chitauri sceptre, formerly held by Loki who used it’s power to cause chaos and brainwash Hawkeye, Dr Selvig and multiple SHIELD agents into being his henchman, had fallen into the hands of the world’s biggest terrorist organization, HYDRA, who began studying the sceptre and finding ways they could use it’s power in their quest for world dominations
HYDRA used the sceptre for several experiments, including creating weapons and trying to create new soldiers like Quicksilver and Scarlet Witch by giving the twins powers. They’d also trialled the sceptre by using it to brainwash innocent people into joining their ranks
