The penultimate season 4 episode of Invincible is now streaming on Prime Video, and it seems Grand Regent Thragg took the accusations that he's all hype a little personally.

Spoilers follow.

Following a flashback to the brutal Viltrumite purge perpetrated by Thragg himself, we catch up with the Coalition as they prepare to take the war straight to Viltrum, where the Grand Regent and a handful of his finest warriors await. Nolan and Thaedus are aware of how dangerous Thragg is, but they figure that with the likes of Battle Beast and Space Racer (well, his gun) on their side, they can achieve victory.

Unfortunately, the element of surprise is lost when they find the Viltrumites waiting for them as they enter the planet's atmosphere, and a bloody battle ensues. The heroes manage to take out quite a few of their enemies, but Thragg is simply too powerful, and Omni-Man resorts to commanding Space Racer to destroy Viltrum itself in the hopes that Thragg and his forces will realise that their efforts to restore the empire to its former glory are futile and surrender.

It does not have the desired effect.

The now vengeful Thragg explodes in anger, decapitating Thaedus and crushing his fellow Viltrumite's head. When Oliver attempts to engage the villain (you were warned, son!), he loses his arm and jaw! As Allen, Tech-Jacket and Space Racer are forced to retreat, Nolan and Mark try to make a stand, but Thragg puts his arm right through Omni-Man's abdomen, leaving his intestines floating in space.

Mark attacks, but is easily overpowered. As Thragg begins to crush Invincible's skull, it dawns on him that only a handful of Viltrumites are left, and he decides to spare his foe's life.

Mark wakes up some weeks later and is relieved to learn that both his father and brother survived their devastating injuries. Allen, who has taken over as leader of the Coalition, informs him that there has been no trace of Thragg and the other Viltrumites since the battle, and Invincible realises that they must have made their way to Earth.

What did you make of this week's episode of Invincible? How do you think the finale will play out?

"While the world recovers from catastrophe, a changed Mark fights to protect his home and the people he loves," reads the season 4 synopsis, "setting him on a collision course with a threat that could alter the fate of humanity forever."

Invincible stars Steven Yeun, Sandra Oh, J.K. Simmons, Gillian Jacobs, Seth Rogen, Walton Goggins, Lee Pace, Jeffrey Dean Morgan, Jason Mantzoukas, Zazie Beetz, Grey DeLisle, Zachary Quinto, Chris Diamantopoulos, Ross Marquand, Khary Payton, Andrew Rannells, Kevin Michael Richardson, Ben Schwartz, Clancy Brown, Jay Pharoah, Mark Hamill, Matthew Rhys, Danai Gurira, and Melise.

Great episode, really had you feel how powerful Thragg is!

@Wahhvacado - FR. When he didn't even flinch at Mark's first punch, I thought that'd just be a nod to the audience that he's OP, and then he'll show weakness later. But he maintained that level throughout.

Makes sense why Conquest backed down from him so quickly.

Everyone's gangasta until Thragg shows up and they realize they've been doing some bad cosplay so far. 💪 👊

Random reptilian alien getting its mouth torn open 180? I want a detailed 2,5 second sequence on that nonce, make sure you capture every splatter of that sweet fatality!

Oliver getting his jaw ripped apart? Nah, a close-up of Thragg and two frames before and after will do. Just make sure we show him in a healing vat later.

Disappointing, to say the least. Waste of insane voice acting talents.

I admittedly haven't read the books, so after watching that episode I'm scratching my head trying to figure out how they will defeat Thragg! I was on the edge of my seat this while episode.

Good episode.

This show makes me wish more animated shows would show fight scenes like these. It’s weird watching Superheroes, DBZ, One Piece and more all have such long dragged out fights where barley any one gets dismembered or bloodied up.

Not what I was expecting ... probably not what anyone was, considering the shadow silhouette we've seen for a while. Interest certainly piqued, if only for all those little details. Mihawk's eyes, Robin's nose, ancient giant horns, wings, tail. Like he's a chimera of a lot of the races, except whatever Apoo is. My weird half wanted him to keep that crown when he finally appeared though. Still feel Teach is gonna be the real Final Boss, and there's gotta be a Davey Back Fight with Shanks somewhere in there to come.

Bestest Doctor Chopper about to get a glow up, though.

@Reeds2Much -

Not sure how I feel about the Forest God theory being thrown around lately in regards to Chopper, tbh. Too many "chosen ones" in a single group, if you catch my drift, in a series that used to be all about outcasts and rejects f#ckin' up the social hierarchy.

But I do love how he quite literally bitch-slapped the demons out of those giants. Probably has something to do with being a DF user, considering how it was Roger and Garp against Rocks in the past, and how during the earlier Elbaph battles none of the warriors hitting the Reversi affected had DFs themselves. Plus, whatever Nerona said about expecting that it wouldn't work on Loki and Luffy.

Just one more day before the story continues, and with no break next week from what the leakers have said.

@TemporarilyHere - While I'm in agreement about the whole Chosen Ones thing, to be fair Luffy really is the only one in the crew. Zoro and Sanji are power scaling as they're pulled along in Luffy's wake, while Franky, Brook, Ussop and Nami are the supports keeping the day-to-day rigamarole taken care of. I guess we can count Robin as a Chosen One, simply for her life leading her where she is now probably wouldn't be too different without the Strawhats. More miserable, sure without a doubt, but she'd still be about the Polyglyphs. I just think all Human-Human Devil Fruits would be Mythic types. I mean, would there really be a Human Human Fruit: Type Steve in Accounting?

The whole Reersi thing isn't making much sense at the moment, anyway. Roger and Garp killed Rocks, none of which had DF and Rocks stayed dead, Loki killed Harold and he and Mjolniquirral are with DF and Harold stayed dead, but then as far as I can tell none of the people that killed Broggy and Dorry had DF either and they came back to life, along with the background Reversied giants. For a moment I thought maybe since they hadn't been turned for so long, but then Rocks wasn't either. I guess Harold wasn't really Reversied, and was just compelled to be evil by the mark. Maybe I just missed something. I was pretty psyched to see Chopper bitchslap a demon outta giants like my nona on any given Sunday.

Hopefully more will be revealed, but as of today Imu just steam rolled over so many people. That last page

@Reeds2Much -

The size scaling in Oda's paneling ever since we came to Elbaph is some straight up God Of War type shit, and I mean that as an absolute compliment.

Plus, how Imu simply tossed our boy's top 2 to the side like they were nothing is enough of a flex to shut twitter's f#ckin' power-scalers up.

Oh, what's that? Racist Zoro is stronger than Sexist Sanji, you say? Well, now they're both nothing. Scrubs. Betas. So f#ck your senseless squables, and [frick] their Captain Crackhead and his band of Lunatics while we're at it.

@TemporarilyHere - So I'm guessin' that they're twins and Imu is a god of Order while Nika is a god of Chaos. Lawful Evil vs Chaotic Good and such. Kind of can't wait to watch them bounce off each other.

While I do wanna see these two interact and get the actual backstory between then, for the love of God...

Elbaph turned into Loki's flashback, which turned into Harald flashback, which turned into Rocks flashback, which turned into God Valley...

Please, just focus on our Sniper-nocchio earning his moment in this place of his dreams, that's all I ask.

Great episode. Lots of death. Thought Oliver was a goner. If it’s been weeks, and it takes weeks to get to earth. It’s not sounding good for the ppl back on the 3rd planet from the sun.

Also kinda feel like those darts should have been kept secret and used in Thragg who wouldn’t have suspected it, now he knows and he’ll avoid them.

I thought Season 4 was an improvement after a disappointing Season 3, until these last two episodes. I'm sure I am in the minority, but I think the overly long, drug out fight scenes are just boring at this point.

@Skestra - Same with Conquest (Jeffrey Dean Morgan) trying to crush Mark (Steven Yeun).

Straight out of Negan (Jeffrey Dean Morgan) bashing Glen (Steven Yeun) in The Walking Dead.

Such a wild ride. I was wondering if they'd do the whole fight in a single episode and they pulled it off nicely.

Thragg: Nope!

Also Thragg is like that end game boss who pops up here and there during the story
