>>281167518it's definitely a powerup, but it's not a good powerup for them in universe. obviously we as readers know that it can be used whenever he's in danger going forward, but for them, it's risky as hell to rely on. if he faces off against a tougher opponent, there's a good chance he'd just flat out die rather than go unconscious, and that would end up killing both of them. I highly doubt we'll see them abuse this by having him purposefully lose consciousness so she can take him over completely and decimate any enemy they encounter. after this they'll probably both agree that he needs to get stronger
>>281174988yeah, it is super cool. I wish we got to see a bit more of it though, I'm curious how the actual transformation looks. is she actually dripping blood all over him, or is that just a visual representation of her spirit or whatever taking him over. I also wonder what's up with her head. based on the blood dripping out of her eyes, I assume she's still looking like this underneath her face, but is that just how she is, or do they need to get more parts back
