So, I remember reading a while back some Black Panther comics but I remember that in the comics T'Chaka (father of T'Challa the current Black Panther) was killed by a character called Klaw. After doing some research, I found that in the comics:
"Explorer Ulysses Klaw finds his way to Wakanda, and covers up his work on a vibranium-powered, sound-based weapon. When exposed, Klaw kills T'Chaka, only to see his "sound blaster" turned on him by a grieving teenaged T'Challa. Klaw's right hand is destroyed, and he and his men flee."
However in "Captain America: Civil War" we learn that T'Chaka was killed in a conference by a terrorist attack with the sole purpose of trying to make the "Winter Soldier" a scapegoat. We learn that it was "Helmut Zemo (Baron Zemo)" that killed T'Chaka. Similiar to the comic books we find that T'Challa is also (pretty much) a teenager and a 'grieving' T'Challa tries to make it his sole purpose to kill 'Bucky Barnes' (The Winter Soldier).
I understand that the new fantasy/science fiction film, "Black Panther" (2018), is likely to follow on from the plot of Captain America: Civil War, because all new Marvel movies will progress on to Phase 3 ("The Avengers: Infinity War"). But I legitimately can't decide; who killed T'Chaka?
