Should be noted that closed captioning never refers to him as Kang. It's always "He Who Remains". Considering all the multiverse stuff he should probably be considered a distinct character in his own right and it might not be proper to specifically call him Kang to contrast with his upcoming parallel forms that are likely to be completely different.
