Saitama shows up suddenly in your verse

[AquaWaifu]

He shows up in an event where the most people are there to witness him and be shocked by him if said verse is not up to his level of AP.

So for example, One Piece, Saitama would sudenly appear at Marineford and knock out Akainu who got pissed by this bald guy suddenly in the way of him attacking pirates and refused to move.

 

[LordGriffin1000]

I have the perfect moment for Danny Phantom. He appears in the final episode and one punches the Disasteroid leaving every shocked given no man made weapon can destroy it and no ghost can touch it.

 

[Randomlamdom]

Puella Magi Verse: the most people in a big event would be the magia record fight against Walpurgisnacht, what happens depends on how fast he goes, if he goes max speed at start he instantly destroys her

If he slows down for long enough he goes to one shot but gets mind haxed, is used to destroy the city and then has his soul eaten

 

[The_Calaca]

Saitama would do nothing to most logias, and seeing some of them have some form of Durability Negation and are faster than him, he's dead.

 

[Ionliosite]

Dragon Ball: Yamcha one-shots.

Saijaku Muhai no Bahamut: Sacred Eclipse passively mindhaxes him.

FLCL: Atomsk goes for the succ.

Ichiban Ushiro no Daimaou: Even The One (Ichiban Ushiro no Daimaou) nukes him.

I also have Shin Megami Tensei and Digimo, but we all know how those go.

 

[Ricsi-viragosi]

Eh, not many of the verses I follow would get shocked by him...

In Ergenverse he'd be fodder against most. He could appear at some points against a core level enemy of something, but he'd most likely get possessed.

In The Gamer, he could potentially beat the shit out of The President until he runs out of money. After that point Han has control over pretty much everything.

In RPC there isn't a set story progression, tough his existence would be pretty preoccupying for the Authority. Might bribe him to work for them tough.

In D.I.C.E. law manip would stop him from ever interfering with anything major unless he got a dice and became part of the game.

In Sakura Dungeo: At any point it applies, really.

In One Punch Ma, he one-shots himself because he can mone-shot his self from a day before, shocking everyone.

 

[Ricsi-viragosi]

FLCL: Atomsk goes for the succ.

Ichiban Ushiro no Daimaou: Even The One (Ichiban Ushiro no Daimaou) nukes him.

Doesn't he just blitz and one-shot both of those?

 

[KnightOfSunlight]

Devil May Cry: Massively outhaxed and outsped (reaction wise) by DMC3 characters, though the AP proves to be an issue until DMC1 when Dante goes Sparda DT and annhilates him with a flick.

Nasuverse: Massively outhaxed, even by most low tiers. Becomes an absolute meme by the higher tiers.

All I've got for now.

 

[The_Wright_Way]

Guys. He's not trying to solo the verse.

 

[Schnee_One]

Attempts to be a hero by saving the InFAMOUS verse from the Beast

Fails miserably

 

[Greenshifter]

Ben 10: Shows up when Vilgax attacks the earth and demands that the greatest hero of earth faces him, while Team Tennyson comes up with their plan to hack the Omnitrix, Saitama just kills Vilgax and calls it a day.

Because of this Kevin is never transformed into Colossus Kevin and since Saitama probably won't be hanging around with Team Tennyson at night-time, they get attacked by Charmcaster and Hex who canonically kill Gwen since Kevin isn't strong enough to defeat them (alternate timelines), transform Kevin into some stone monster that obeys them and capture and torture Ben.

Saitama finds out, oneshots Hex and Charmcaster but Kevin remains on their side. Due to Gwen's death, Ben puts the blame on himself and doesn't want any teammates anymore and thus Saitama goes to another city.

Aggregor steals the Andromeda aliens' power and almost gets omnipotent power but Paradox brings Saitama to the fight and Aggregor gets oneshot (keep in mind that Ben also never gets the Ultimatrix). After another run-in with Charmcaster, Ben forces her to transform Kevin back to normal.

Ben tells Kevin that Gwen died, this causes Kevin to go insane and absorbs everyone's power. Only this time Ben isn't held back by Gwen and kills Kevin.

Dagon may or may not appear, in the case that he does it is likely Ben gets Ascalon and uses it's power to resurrect Gwen. Gwen being devastated that Kevin died never wants to talk to Ben again, this causes Ben to go insane and when he finds out about Maltruant's plan he wants to work with him.

Meanwhile Paradox collects multiple heroes from all over the multiverse to stop them, most notably Saitama and Rex Salazar. Ben uses his more haxy aliens to kill Saitama. Rex either destroys the Omnitrix and locks up Ben for the rest of his life or Ben wins the fight, goes back to the beginning of time and backstabs Maltruant and creates a multiverse where he is the ruler and everyone is forced to drink smoothies.

If Dagon did not appear then Ben grows insane with trying to bring back Gwen to the point he tries to steal Professor Paradox's Chrono-Navigator to undo everything and eventually becomes Eo.

 

[The_Calaca]

Dude, paragraphs.

 

[Ionliosite]

Doesn't he just blitz and one-shot both of those?

As I said, Atomsk uses his 4-C succ as his first move, so Saitama loses there.

If The One isn't enough, The Law of Identity can perfectly do the trick.

 

[Schnee_One]

Subsonic vs Rel+ means Saitama omega blitzes first

 

[I'm_Blue_daba_dee_daba_die]

The Legend of Zelda: (Thinking of TP for this):

Well, if he is there in Ordon village, he should be able to stop king bulbo from kidnapping Link and the children. This leads Link doesn't meets up with Midna. Meanwhile, if this keeps up for longer, then Zant eventually decides to step in and kills saitama, likely turning link into a wolf right there and there. Since he doesn't have Midna to help him understand what happened, he can not become a human again. Meaning, that Ganondorf won and Hyrule is turned into darkness.

So basically Saitama being in TP would be a bad thing

As for BOTW:

Saitama would be a big help when Ganon invades hyrule, taking out guardians and his army. BUT Ganon would eventually hit him and kill him, plus, I don't think he can save the champions. So the plot continues.

Actually, maybe he becomes a Champion himself and has his own divine beast

Warhammer 40,000: Saitama lands in an Ork domain where he has the time of his life until he gets stomped into the ground.

Hunter X Hunter: Saitama may solo (except the Dark Continent) if he's serious but he might get nuked and dies to poison off guard. Especially if he willingly takes the nuke.

Saint Seiya: Erased by a Gold Saint

Magi: Gets yeeted by a god tier mage like Aladdin, Solomon, Ugo with prep time, David.

Welp read the OP wrong.

In HxH it can vary depending on various things like the possibilities are huge.

Warhammer one way or another he will die if he attempts to kill "monsters"

Saint Seiya might recruit him as a Saint depending on how he acts but his strength will definitely be recognized.

Magi he'll just party with Aladdin and co all day.

 

[Spinoirr]

RWBY: sitamia gets the same felling as his verse but worse. Salam isn't immortal because saitama not giving a damn some how teachs her the meaning of life and death because he is sitaima and can inspire pepeole even if he doesn't care

 

[LordGriffin1000]

Chaos Legion (Game): He shows up during the demon invasion of a city and blitzes the demons whivh will surprise them... But that's all since the demons are comparable to Sieg Wahrheit's legion aka High 4-C. So while he can't harm them they will be surprised by his speed.

 

[Ricsi-viragosi]

As I said, Atomsk uses his 4-C succ as his first move, so Saitama loses there.

If The One isn't enough, The Law of Identity can perfectly do the trick.

Unless it's passive, no he isn't. And Saitama does not need to beat everyone, he just appears against a villain in the series and tries to battle them in a situation that would shock them.

Same way him appearing against King Piccolo is a fine scenario, despite him becoming a fodder later on if he doesn't learn to use ki.
