:Only when he doesn't fully manifest himself in them.

Which didn't happen with Robbins. It's also been hinted by Dormammu himself that he needs to possess one soul at a time to completely manifest:

True. But as i explained above it depends how much Dormammu manifests in them and how much power he gives them. Also it was stated that Dormammu fully manifested himself in full power while possessing Hood, so there is info backing that up - scan.

What did happen is that Dormammu offered to Robbins the full power/control, but he refused:

They show very explicitly later(Right before Dorm being exorcised) that Dormammu wasn't fully manifested and still gaining access:

Doctor Strange himself said to Robbins that Dormammu's promises, in the end, are all falses:

So even if Dormammu can completely manifest himself in a body and maintain full control of his powers, Robbins wasn't the case.

Kinda obvious. :D

Still shows a gap between Dormammu himself and his hosts though.

No offence, but there is no concrete information in your scan showing that. He just talks about possessing more souls to spread the message and that's it.

Like I said, it hints that and not confirms. I'm not trying to bypass that as an indisputable proof, only something worth mentioning. Still, Dormammu showed that need to spread the Mindless Plagues to render his influence on Earth, so this might follow the same concept. My focus is more on the Hood himself anway.

Hood didn't refuse those powers, he simply didn't do what Dorm hinted, gain skills to master those powers and that's it. He had power but not the skills, which is always the case with magic powers of skyfather tier, i mean just look at Thor and Odinforce, mastery = more potent usage of it.

I should've made my point clear then. Dormammu did offer the Hood to gain completely mastery/control of his powers, but that reflected in how much he knew to use it. Jennifer Kale wasn't that different, for example. That's also a very shitty comparison. Thor has a god-like biology and some considerable knowledge of the mystical/cosmic energies....The Hood is just an ordinary human how basically knows nothing of magic. Besides, do you know that reflects on my point as well? The Hood can have all of Dormammu's energies available to him but without the training, disciple and knowledge(Which he has none), Robbins won't be able to channel/access them:

Why do you think novices have problems to do the most basic of spells or cast the stronger ones? Imagine Robbins who has access to Dormammu's energies, yet his mystical training is beyond pathetic. All practitioners can potentially drag upon infinite amounts of energy depending on the three factors I mentioned. So no, Dormammu may have given a chest of gold to Robbins, but the later doesn't know how to open it.

Still your scan shows none of that, post more proper evidence indicating that.

It does show that, but you're the one ignoring it and if we're gonna argue semantics, nor your scan shows that Hood had the full power of Dormammu or prove that he kept his word....Dormammu says that Robbins asked for all "secrets" of the Dark Dimension and not all of Dorm's own power, it also says that Dormammu gave him the power asked by Robbins yet doesn't mention if it is all of Dorm's power(Excuse me, The Dark Dimension) or how much Robbins asked(Secrets aren't power after all). I know Dormammu promised him all the power of the Dark Dimension in New Avengers#46, but did Dormammu really do that? Especially because Dormammu said that will need to guide him and Robbins was clearly fighting against his influence most times:

They explicitly said and shown that Dormammu is still gaining access through the Hood's body, so he wasn't fully manifested yet. Hood didn't have full-control, remember? It's very clear by that Hood also didn't know how to full-access Dormammu's energy/power right off the bat as well and this can be when he was slowing taking different, more demonic and powerful forms before getting in one that resembles more Dormammu himself:

So makes sense for Dormammu not being completely manifested. It's already been shown by the other comics that after possessing a body, Dormammu takes time to reach his full-power and control:

And this was when inside Strange's body, which is someone whose mystical powers and affinity are far greater than Robbins. My other scans above even happened after your own and fiding/battling Strange, which is part of the promised made by Dormammu(Yet Robbins still didn't access the full-power). You said that Dormammu gave Robbins his full-power, but can you prove to me the later even knows how to access/channel all of it?

Read your scan again, Dr. Strange simply hints on classic cliche that bargaining with demons doesn't end well.

Also Hood's goal was not power actually, his goal was something different. Plus Dormammu is not your average demon, this guy can give skyfather and the likes hell, he is not the lieing type guy.

Like you said: "Post more proper evidence indicating that." Especially because there are many instances showings how tricky and dishonest Dormammu's deals are, for example with Meggan:

And Strange knows Dormammu better than anyone. I prefer to not enter into a debate about where Dormammu's power-level ranks in comparison to skyfathers(Most because there are four to five different instances portraying Dorm as more powerful, lel) and this has less to do with power, but more how twisted and evil is the personality of Dormammu. Aren't you the one who said that my scans of Dormammu being "Worse than a demon" was about his personality? Then wouldn't be beyond him breaking his own deals. Especially with someone that he doesn't respect like Strange and didn't think twice before replacing him for another person, basically breaking their deal:

Heck, we can even take Dormammu himself saying that can't get out of his realm even when the Hood was still his pawn for Dorm to possesses him like in the New Avengers:

Which would indicate once again the form assumed by the Hood wasn't really the true/real Dormammu.

Which depends on the context.

And the context was that Dormammu wasn't fully manifested on Robbins.
