Warning: The following contains possible spoilers for Marvel's "Captain America: Civil War."

One of the criticisms lobbed at Marvel's Cinematic Universe has been the lack of dramatic stakes. At no point in any MCU film has anyone ever really expected Robert Downey Jr.'s Iron Man to bite the dust or Scarlett Johansson's Black Widow to be taken out. Not even Loki or Agent Coulson stays dead. But 2016's "Captain America: Civil War" may change that perception.

One character death in the film has already been leaked and now, according to Heroic Hollywood, fans should expect another.  

"T'Chaka. Yep, Black Panther's daddy," Umberto Gonzalez wrote.

"...For those who don't know, in the comics, T'Chaka was the Chieftan of Wakanda, pledged to protect the sacred metal known as Vibranium. From an early age, he excelled in the ways of magic and took a stance to preserve Wakanda's heritage by honoring the 'old ways' of magic use despite the technological advancements of Wakanda.

"Since Wakanda was independent with no ties to any other nation he was eventually called to a UN meeting in hopes of other countries trading with them. He refused however and was assassinated by Ulysses Klaw while he tried to protect his wife and children. His death made his S'yan the Black Panther. S'yan was later succeeded by T'Challa."

T'Challa AKA Black Panther will be played by Chadwick Boseman in "Civil War" and a solo movie in 2018. His exact role in "Civil War" is still unknown but it is assumed that he will be responding to the vast quantities of Vibranium stolen from his country by Ulysses Klaw (Andy Serkis) and Ultron (James Spader) in "Avengers: Age of Ultron." Whether or not he directly enters the fray between Captain America and Iron Man is still a mystery.

"Captain America: Civil War" will hit theaters on May 6, 2016. "Black Panther" is currently slated for a July 6, 2018 release date.
