N'Jadaka (Earth-5180)

"I waited my entire life for this. The world's going to start over. I'mma burn it all!"

- - Black Manta to Black Panther

Prince N'Jadaka, also known as the Black Manta, was the middle son of King T'Chaka, brother of T'Challa and Shuri, brother-in-law of Ororo and uncle of Azari. Envious and cunning, N'Jadaka betrayed his family by helping the mercenary Ulysses Klaue in an assassination against his own father's life in order to rule Wakanda. Rallying a legion of his own soldiers, he attempted to kill his family, which costed T'Challa his hand when he tried to save Azari, but also costed Manta's life.

Early Life
N'Jadaka was born in 1979 to King T'Chaka and Queen Ramonda, being the second in line of succession to Wakanda. He showed aspirations of leadership since he was little, but was sidetracked by his brother, T'Challa.

Assassination at the UN
Tired of awaiting, N'Jadaka hired the mercenary Ulysses Klaue to murder his father and brother at the peace talks at the United Nations Headquarters in Vienna, Austria, planning on starting a war against the rest of the world's countries to usher a new era for Wakanda. Thinking he successfully had both killed, N'Jadaka took his nephew Azari captive, in order to "convince" Ororo and Princess Shuri to cooperate with him.

At his new rule, N'Jadaka stole the ancient armor of wisdom of Birnin Zana, naming himself the Black Manta, which he hoped to turn into the new order of Wakandan kings. One of his first orders was to grant M'Baku and his tribe access back to Birnin Zana in exchange for complete obedience, which he accepted.

Battle of Wakanda
"I changed, dear brother! And before this day is done, I shall be a King -- and you and the rest of the family shall be dead!"
