If you know any, Do it xD

Anyone he isn't immortal just super strong

Well just throwing an immortal at him is not gonna hurt him xD

Shaggy

Orochi or Gyro Gyro

Hmmmmm, Maybe

heaven ascended dio

Hmmmmm

well im not wrong

think about it

your mom tryin to bang him

I can neither confirm nor deny xD

Giornio

Hmm, You might be on to something xD

Goku? Nah, Saitama can probably whoop him before he even goes Super Saiyan 1 xD

Well, Actually turns out, Zeno is canonically slower and weaker than Goku, The only Godlike ability he has is Erase

Isn't that what okayasu is only good for

Yep xD

I feel like Nanika from hxh did that.
Nanika could one shot him with a wish from their brother :)

Eh, You're not wrong xD

Himself in a parallel universe. They found a way to meet because they both get very bored.

Saitama did that too, Not to himself, But he did just walk through some dude's personal universe

Update: Arale Chan, being a gag manga character, is unbeatable and therefore would be able to do this to saitama with ease

Bruh

Genos...

Seriously? 😑

idk .,.

Of course, no one will be able to convince you that someone could do this, so why even ask?

A couple of people did, Check the higher comments

dragnoc because he's immortal and is much more powerful than this guy

Bruh

I'm serious

Immortality ain't gonna do sh** if they're just gonna stand there and not die.
And how strong is Dragnoc anyway?

God level he can kill dimensions in seconds but is sometimes to humble to do so

Bitch, Saitama can WALK THROUGH dimensions!

Well have ye watched him kill gods because dragnoc can do that

Same with Saitama

Dragnoc kills immortal people

That is literally not possible

That's why he can severely hurt saitama he can do the impossible

So can saitama

Y'know that literally means they weren't immortal in the first place, Right?

They were immortal but not immortal? That makes no sense

If they can regenerate or have limitless longevity, They're pretty close,
But if they have the ability to die, They ain't immortal, The whole point of immortality is to lose the ability to die!

He kills things that can't die

Of course Lord Frieza would have done this in a heartbeat.Frieza could destroy a planet at his weakest, and is far faster than any mere human could hope to be.

Bruh, Nice try xD
