Could they beat the Avengers or Justice League?

It's even more extreme than that, because unless you have the special power, you can't even see Aizen or other shinigami. So he could cut off heads without them knowing what is going on.

Hulk can see ghosts

Freiza could blow up the sun, depowering Superman. That's a gg right there against the League if they don't have a reset button handy.

They're based, so yes.

>Freiza could blow up the sun
He can?

He can now, anyway. That was a Perfect Cell level feat at most and current Frieza only loses out to current Goku and Vegeta from his universe. He can take a savage beating from a god-level existence without dying on the spot.

Even then, time stopping DIO doesn't have a lot of his vampire shenanigans. He really isn't all that powerful compared to these characters. Hell, most JoJo characters are actually really weak outside of their series.

>Eh, guys like Hulk and Superman are pretty fucking tough

Hulk would be screwed if the planet exploded, because I'm pretty sure he still needs to breath. Frieza just needs to blow up the earth to deal with him. Superman is ok, until Frieza blows up the sun lol

Aizen could just use their strength and trick hulk and superman into fighting their own teams.

No one else in the sinister six would stand much of a chance.

They could beat the Teen Titans.

No. Especially not against the Justice League which is stacked with heavy hitters. Freeza wouldn't even be able to hit Martian Manhunter if he went intangible and then he could just attack him with his psychic powers
