… Lemar.
When Lemar Hoskins/Battlestar was introduced alongside his bestie John Walker, I already was a little … concerned. Lemar was the latest installment in the Black Best Friend MCU division, and that was already a pretty cringe development even if Sam Wilson was one of the titular stars of the show. Of them all, only Sam has been allowed to really shine as his own person outside the “sidekick” label. Even Rhodey doesn’t get to do that.
Lemar is introduced as supportive to John. They served together in war, and Lemar clearly sees a noble version of John that we as the audience cannot compute. They fight together and, in many ways, Lemar is the voice of reason in their personal dynamic duo. This, of course, makes it even more difficult when Lemar is accidentally killed in “The Whole World Is Watching.”
