@Ant No problem. Anyway, this is my second attempt at typing a response...But I'll keep things short since Madotsuki has done a pretty good job at responding to the questions. Anyway:
1) Before I even answer this, I would like to say that some of these questions (including this one) were already answered on
this thread that the OP had made back the. I think that alone should speak for itself which kinda makes this thread a bit useless but regardless... To answer this,
Yes Giygas did retain his old abilities. What makes you say that he hasn't? You might as well post scans and justification to back up your implied claims here. Like, Giygas was growing immensly in power that he was becoming an abstract mass of evil, I don't even see why he would lose such an ability that especially correlates to his concept and existence. The only thing the Devil's Machine does is
contain his form and keep his
sentience in check, it doesn't suppress any of his abilities at all. And before you say that what the profile states contridicts what I am say, it doesn't. "Tremendous power" clearly refers to what Giygas became after the events of Mother; his true form which caused the destruction of the future timeline. Granted, it could use better wording to prevent confusion.
Plus all his actions during the events of the game are done from within the machine, including using mind hax across time, it's plain obvious throughout the text of the game,
even as early as Buzz Buzz.
2) As said before, yes. Again, clearly obvious within the text of the game that Pokey was under the influence of Giygas. Such as Betryaing and taunting Ness, causing inconviences throughout his journey, and especially assisting Giygas throughout, being a
right hand ma. Does that alone conviences you that he was clearly influenced? If not, then I don't even know what else to tell ya. And no, Pokey calling Giygas an "All mighty idiot" doesn't mean anything at all nor does it imply that he has free control or whatever. And even so, he refers Giygas as his
Master and treats him as an Omnipotent evil force; taunting Ness and his party how he can't really win and stuff. As for Mother 3, yes he's still under his influence,
just not directly. Giygas had already corrupted his mind in Mother 2 and as such, there's still
lasting damage of it which is why the action he does in the game happens. I don't how him constructing an empire based off of him is supposed to debunk it, if anything, it kinda further proves my point. He became a dictator of the island and a skillful manipulator. Even ruined a family cuz why not.
3) Basically what Madotsuki said. He was resisting throughout the journey and had to travel within his Magicant to truly destroy the
evil in his mind. Doing so allowed him to destroy all of the evil, fears, and doubts that were within him, allowing him to absorb the true power of the eight "
Your" Sanctuary locations. As for the others, this is likely as a result of Truth's protection and the fact that Ness is the universe.
4) No, he hasn't, but that's irrelevant. The fact is that he has passive mind manipulation, it doesn't need to be displayed in a fight because we've already seem its capabilities outside of fights. Even then, Giygas hasn't gotten an opportunity to even use them in a fight, he was holding back against Ninten and Ness was immune to his mind manipulation, so just cause he hasn't used it in a battle doesn't mean he can't or wouldn't.
5) This is more along the lines of just gameplay. There obviously has to be regular people to interact with for the game to be believable. There doesn't need to be a specific explanation.
6) You mean the absolutely safe capsule? He already has it on his profile lol
7) Probably before 2020
