Because this series is acknowledging King in Black from the beginning, I feel this is really aping both KIB for what happened in it regarding Bob's death, and a Captain Universe influence which had a big role in KIB's climax, but also the third Jeff Lemire Sentry miniseries which was also focused on replacing Sentry, which also happened to have a white blond villain that refreshingly and for a change wasn't Sentry's Void. Unfortunately it seems the KIB plot here might outweight the more Bob-centric comics, regarding how his powers are starting to matter more than the guy. And to add insult to injury, it might even tie in to that event's Thunderbolts tie-in, because Sentry is expected to be used in that movie and Doc Strange is going to feature in the current series, and it's super easy to tie in the KIB-Thunderbolts-Strange-Sentry Vol 4 comics without spending much editorial work. About how Sentry's power remains after his death and powerful villains really want it.
