The Black Viper looked at the empty shell before her, the former Natasha Romanoff or Black Widow. The Viper had lured the Widow with a puzzle designed to attract the attention and efforts of the greatest spy. What the Widow didn't know was the trap had been set from another universe. From the leader of HYDRA from another universe, who happened to be... Natasha Romanoff.

Once captured, the Viper wasted no time linking the Widow to the machine. One which would download all of her memories, all of her knowledge for the Viper's files. As well as the second stage of the program. Of course, it didn't matter how harsh the process was. Which was why the Widow had her mind basically blanked out like an erased tape.

Of course, that lead to stage two. Which was now coming out of the pod before the Viper. The Viper looked into her own face as both of them smiled and saluted with a Heil HYDRA. The Viper asked her Twin, "What is your mission?"

"To return to the Black Widow's World and expand the reach of our HYDRA. Given the modifications of our body and the Widow's memories, we infiltrate and convert all valuable assets. Failing that, prep them for capture and cloning replacement like you did to create me." said the Clone and future Viper in Widow's clothing.

"Good. Time to equip you and return you back 'home'.
