In the MCU, can Killmonger's gold Black Panther suit absorb kinetic energy from Iron Man's missiles and repulsor blasts?
In general can Killmonger's gold suit absorb regular kinetic energy, like T'Challa's can?
Killmonger's gold suit is the exact same as T'Challa's silver one. They are both presented to T'Challa by Shuri during the movie, but T'Challa says the gold one is "Tempting, but the idea is not to be noticed." Here is that clip from the movie.
And seeing how T'Challa's suit is able to absorb a large variety of kinetic attacks, then Killmonger's would be able to do the same.
