The Massacre at the Wedding Party was an attack on members of the United States Navy orchestrated by HYDRA agents by the use of a chemical weapon based on the effects of the Obelisk.


The United States Navy created an anti-HYDRA unit; Pete Leitner was a member.[2]

Obtaining skin samples from a waitress who had been petrified by the Obelisk, Daniel Whitehall wanted to see if the effects could be replicated and weaponized for HYDRA's use.[3]

He assigned one of his top scientists, Doctor Lingenfelter, with finding a way to replicate the Obelisk's effect. With much work, Lingenfelter created a chemical weapon based on the Obelisk's effects and decided to test their creation.[2]


"Somebody help! Somebody help us!"

HYDRA decided to test their weapon at the wedding of Peter and Mariah Leitner. The wedding was attended by many of Peter's colleagues from the United States Navy. As Peter's best friend Schneider was giving his toast to the couple, the wait staff started to serve champagne to the guests and would not allow them any other drink.

After the toast, the guests who drank the champagne started to petrify and died. Some of the wedding guests suffered no effects while others had to be hospitalized.[2]


"There were positives. Many of the deceased were enemies of HYDRA."

Only a total of nine wedding guests died from drinking the poisoned champagne, which did not please Daniel Whitehall. He summoned his top scientists to discuss solutions to solving the problem of fully recreating the Obelisk's effect.

Jemma Simmons had been asked to attend the meeting by Sunil Bakshi and was able to report HYDRA's experiments with the Obelisk back to Phil Coulson.[2]

HYDRA did keep the chemical in its arsenal. It was used by an agent of Octavian Bloom to kill the Baroness, another HYDRA leader.[4]
