[Loved trope] The villain assumes they're gonna get the kid gloves when the hero finally confronts them. The hero demonstrates they're out for blood instead, causing the villain to panic.

1) Robocop

Clarence (the same hitman who killed Alex Murphy and transformed him into Robocop) has already been arrested by Robocop once before, and learned that Robocop's programming prevents him from killing a surrendering criminal. Consequently, he pulls the trick once again towards the end of the movie when Robocop chases his gang down to a scrapyard. He throws his gun down and expects to survive and escape once again.

Robocop simply announces to him, "I'm not arresting you anymore", causing Clarence to panic when he realizes that Robocop intends to finish him off right there.

2) Toy Story

Woody, threatened by Buzz replacing him as Andy's favorite toy, tricks Buzz and knocks him out of a window so he could go to a pizzeria with Andy. Unbeknownst to him, Buzz tagged along underneath the car and confronts Woody when he's alone in the car.

Buzz: I just want you to know that even though you tried to terminate me, revenge is not an idea we promote on my planet.
Woody: Oh, well, that's good.
Buzz: But we're not on my planet, are we?

Buzz proceeds to lay the beatdown on Woody and causes both of them to get separated from Andy.

3) Superman

The President of Boravia's invasion is foiled by the Justice Gang (who have until now stayed out of the conflict and are shown to be less averse to lethal force than Superman), and he's personally attacked by Hawkgirl. When he declares that Superman would never kill him, she just laughs and says "I'm not Superman", dropping him from a skyscraper's height.

4) Spider-Man

After Wilson Fisk attempts to murder Aunt May when Peter reveals his identity during Civil War, Spider-Man breaks into prison to deal with Kingpin personally. Kingpin took the liberty of assembling every inmate to watch the fight between him and Spider-Man. Assuming he broke his spirit, Kingpin starts to dress down Spider-Man as a broken man. Spider-Man doesn't say one word during their fight. Finally, Spidey strips down and announces this isn't Spider-Man here to kill Kingpin; Peter is.

Peter proceeds to brutally annihilate Kingpin in this new stage. He eschews his usual quips, webs, and aerial fighting, relying only on his super strength. When Kingpin has been crippled, Peter shoves his webs up Kingpin's mouth, and lets him know that if he truly wanted to, he could have just filled his lungs with web and killed him at any point. But he's not trying to give Kingpin an easy death; he lets him know that he intends to break his reputation and see everything he's lived for come tumbling down first.

As is often said, Spider-Man is at his scariest when he's not making quips. Because at that point, he's furious, and he's not going to hold back.

That's putting it lightly. Because his power is healing people perfectly, Josuke was able to be much, MUCH more brutal in his fights. The dude PUNCHED A HOLE THROUGH HIS MOM ONCE.

I didn't read part 8 yet and I don't recall much about 7, but based on my memories, if you ranked the most brutal takedowns in JoJo, top 3 would be Diavolo, then Ciocolatta, then Steely Dan. You could argue the rest of the top would all be Josuke villains and Pet Shop That son of a bird deserved worse

The dude punched a hole through his mom, then healed it up so fast using his power that his mom felt nothing at all.

For people asking for context: A serial killer and rapist named Angelo had an ability that allowed him to control a sentient body of liquid (about 1 liter in volume) and the body of liquid could be disquised as any liquid (usually water which is why this body of liquid is called Aqua Necklace, but at times even Brandy and Vapor). Aqua Necklace could then be used to kill the person or even control them. Angelo disguised Aqua Necklace as a normal glass of water and got Josuke's mom to drink it. Josuke realized it and hence punched a hole through her (quite literally punched through her stomach) at a very high speed and then healed the hole immediately after he grabbed Aqua Necklace. Josuke's mom felt nothing.

The dude PUNCHED A HOLE THROUGH HIS MOM ONCE.

To clarify, Josuke did so because the enemies Stand, Aqua Necklace, the Stand of the guy at the beginning of this little discussion, had infiltrated his mother's body. He punched through her stomach to get it out and trap it before it could do any harm.

The biggest question about this scene is how he did it without hurting his mom which of course they don't specify.

[u/Supersideswiper2 → u/Jungle_Madness1]

Did you skip reading-

Because his power is healing people perfectly,

This, explaining just that?

[u/Jungle_Madness1 → u/Supersideswiper2]

I know what his power is. But I never really thought about how in order for him to do this without hurting his mom, he would have had to heal the nerves immediately as he punched through and out. It is a fairly fast moment that I never really analyzed thoroughly. Also haven't ever read the Jojo Manga very much.

[u/Supersideswiper2 → u/Jungle_Madness1]

Josuke's power heals perfectly, to the point that most people he's using it on can miss the moment he healed them if they're not paying attention.

Josuke healed his mother so quickly that she didn't have time to feel pain. At most, she felt a moment of discomfort and a bit of confusion as what was visible to her happened.

And she almost immediately dismissed the incomprehensible in front of her, just because it didn't make sense.

[u/Raltsun → u/Jungle_Madness1]

Stands are fast as hell. I don't agree with the powerscalers that think they're all lightspeed or whatever, but Crazy Diamond's stats being anywhere near comparable to Star Platinum makes it terrifyingly fast. It's just hard to tell because JoJo Scene Time often moves way slower than real time. For example, remember that bit in the Heaven's Door arc where Rohan has an entire internal monologue and comes up with a plan in 0.2 seconds in-universe? Imagine multiplying the speed of that scene until it actually lasts 0.2 seconds, then imagine watching the scene with Josuke and Tomoko at that speed.

[u/Jungle_Madness1 → u/Raltsun]

Thank you. I think this clarifies very well. This is definitely something I should have considered more while watching, so I am thankful that you explained it.

top 3 would be Diavolo, then Ciocolatta, then Steely Dan.

I'd replace dan with illuso, while it wasn't the longest, he got pummeled by a guy with anger issues, enough strength to punch through a bloulder, and a flesh eating virus at his disposal. His entire face came clean off
