One of Demon Lord Odio's avatars is in fact Dio BrandoThink about it; in Japan Dio's name would be written Brando Dio... and his entire childhood was meant to make him into a bitter and hateful man.
The Medieval Chapter was one big Evil Plan by the former Demon LordInevitably someone would strike the Demon Lord down, and he knew that. So what did he do? He prepared for someone to continue his legacy. He forged magical statues with pinpoints in time so he could conquer more. Then he attacked again. He captured Alicia, drew heroes towards him, and he was - physically - forevermore vanquished. A small sacrifice if he could forever scar humanity. At this point, he probably knew Hash, honorable hero that he was, would not be satisfied with such a feeble show of strength by what he knew was an opponent worthy known of being a demon. He would search for the demon, and Odio would try to feed on any hatred left in him. But what's this! Hash had a plague. He was unfit to even fight. Tch. Foiled by the noble sacrifice of the old guard. But even still, they had brought young blood... Straybow, Straybow was the target. Odio seized the opportunity and unleashed Straybow's resentment and hatred towards being second fiddle. At this point, he probably wanted Straybow to be his successor, to go through time and conquer with the statues he'd left behind. But Oersted came. He saw. He fought his former best friend. He lost his love. He lost everything. Odio's gambit paid off bigger than he ever imagined, as now, Oersted's sense of justice was ripe to be twisted by hatred... and he turned on mankind.
Orsted is an Apostle and the demon statue was one of the Godhand in disguise
Oersted/Odio is The Operator/SlendermanJust listen to that static sound during his chapter, especially when he finds Alicia.
Should the game gets a remake/sequel...Then we will get another Odio incarnation to fight aside of Oersted... but Watanabe. Pissed off that he's treated like the universe's punching bag who's played for laughs rather than drama, he hated all those mistreatments and true to Oersted's words, 'As long as there is hatred...', Watanabe will gather all his incarnations which were abused and became the Demon King to make the world pay for laughing at his misery. The only probable exception is the Watanabe at Akira's chapter, since he seemed content enough.
Watanabe is the one who set Oersted up to fall!In every era, in every setting, that poor green-haired kid suffers the loss of his father, and the chapter's hero just... watches. When Oersted kills Watan Naibi in the tournament, he's finally had enough, and decides to utterly BREAK this hero... ultimately making the situations that killed his father in the first place. Dumb kid.
Akira is meant to be the default protagonist of the final chapterWhen Oersted first visited the room of statues, the Odeo statue will always be at the center. And when you pick any protagonist, their respective Odio incarnation will take the center place, and the Odeo statue will replace that Odio incarnation's former place. So they were thinking that by default, Akira would be the one leading the attack against Oersted. But then, the game was quite open-ended, so it's not seen at the get-go. Tying into that is Akira's special dungeon. It is the only place that gives the protagonists any idea as to what happened in Lucretia, other than the fish in Pogo's dungeon, who really only tells you the name of the place. So, Akira learns Oersted's name, and can probably piece together some of what has happened. It would make sense for him to confront Oersted about that. Another part is the series of non-battle pictures in the ending credits. While it would end in a sight in Lucretia, the order will always be Xin Shan Quan successor -> Pogo -> Sundown Kid -> Cube -> Masaru -> Oboromaru -> Akira. Any reason in particular why Akira is always the last? Even there are other series that put the main hero last in the "Where Are They Now?" Epilogue. And like the first one about the Odio incarnation statues, the pre-credits epilogue usually shows the one chosen as main protagonist last, however, the credits pictures that doesn't show battle scenes will always put Akira the last. So...?
Clockwerk is one of the incarnations of the Demon King Odio.Given the fact that Clockwerk is immortal by the his hatred of the Cooper clan, he may be a part of a series of owl drones designed by an unknown time traveler to observe the Coopers of different time periods. The tenth one that is created becomes Clockwerk as his model number is OD-10.
