"Orochimaru knows how this move works therefore he will take precautions. Moreover as seen in the show, Zeno gets surprised by anything." Substitution Jutsu (Or Body Replacement Jutsu) is literally just the User moving something in place of where they once were in an instant. Seeing as Zeno's Erasure isn't projectile based, again, this would do nothing. Also even if you know how a move works, how does one prevent someone from squeezing their hand? What?
When has Zeno gotten surprised by anything? Pleasantly surprised, yes, but there has never been an instance of Zeno going "NANI".
"Do to the fact Zeno got surprised by substitution. He will stop the move from completing. Also, I never said that the move will not work on Orochimaru."
Again, Substitution will do NOTHING since Erasure is not projectile based and as such, the log-where-I-Was trick will not work.
"That's something that Bulma will do yet do to Goku and Vegeta pride. They will stop her so they can have a fight to test Orochimaru out."
No. No they won't. You're overblowing their egos again; something that's been debunked LONG LONG ago. Goku, maybe, he's fairly dumb in Super (Despite his actions at the end of Z), but Vegeta has little to no pride anymore. That's his whole character arc; he's left his "Royal Pride" behind in favour of protecting his family. It's why Vegeta humiliated himself to please Beerus.
Plus it's not only Goku and Vegeta watching it. Champa, Beerus, the Angels, competent Gods of Destruction, etc. they will all be watching it due to their notoriety now.
"Lol.. That's out character. We never seen Shenlong counter King Piccolo's attack due to Kami being stronger than him. They are neutral in any giving situation."
This is a verse vs a character. EVERYONE vs ONE. Everything is already OOC. You can't just say "lol no" and give an explanation that's already accounted for just because it suits your needs. Every DB Character vs Orochimaru, that's the thread. Not "Everyone except the Dragons because they no longer count as characters for some reason vs Orochimaru".
"I never said anything about gaining powers. Just the title. As seen in the series, GP and angles have respect to him because of his ruling. Do you think they will obey a person who got dethrown or the new ruler? That's the powers of the Super Dragon Ball's."
This basically tells me that you have absolutely no understanding of the Dragon Ball Lore. They fear and respect Zeno because he has the power to erase anything and anyone in a single instant should he wish. Universes, people, planets, galaxies, doesn't matter. He can erase it all. It has nothing to do with the title of Omni-King.
"Again! I never said anything about him gaining powers. Just the title, "King of All." We don't know wants going to happen to GP if he will follow Zeno or Orochimaru. Unless you think Zenos will is the same as GP. Just like Black Zetsu."
And you again don't seem to understand that the title of Omni-King is NOT what makes them follow Zeno. It's Zeno's power that they respect and fear, not the mere title.
"What's the point of that he will just ask GP to teach him the Hakai and other abilities that he is missing. In fact, Orochimaru will tell GP to go foward in time and to the wish again. Then ask to get same powers of Zeno. Even the strongets will go cry in a corner. Zeno is just a kid. Since he was dethrow. GP and the guards will just ignored him. No more Rare Candy for Zeno."
See this would make maybe a little sense if it weren't for the fact that this is an All-Verse vs Orochimaru match. Even if Orochimaru got the title of Omni King, as per OP, the Grand Priest and every Angel would still be out to kill Orochimaru.
Also doesn't change the fact that Zeno can still erase Orochimaru, title or not.
