The villain of the day has dropped a bombshell revelation. To show the reaction shots of all the protagonists at once, the screen is split into sections, with a reaction shot in each section. The reactions may show up one at a time and accompanied by a clang sound effect.
Alternatively, the split screen may show the faces of all of the protagonists as they act in unison. This is especially popular in shows with Combining Mecha, Colors or Powers. Just about every Shōnen series does this when a particularly harsh blow lands. To be fair, most anime where there is any sort of competition will show something like this.
A typical Split Screen is just two people and a thin vertical divide between the two halves. The Split-Screen Reaction often has stylized divisions at strange angles. It may not even be a true "split", but a series of picture-in-picture bubbles that pop up. (Also see Odd-Shaped Panel.)
Characters with Medium Awareness may be able to use the split to interact with the other characters where it wouldn't usually be possible.
Compare Multi-Part Picture.
If they all have the same reaction, that means it is also a Universal Group Reaction.
- Mechamato: Two in episode 4. When Mara suggests they look for Mr. Jamie, their oddly absent teacher; Amato, Deep and Pian's shocked faces are shown in respective panels on screen as they exclaim "SAY WHAT?!" in unison. Then in the library, when Amazeey announces Mara, Amato, Deep and MechaBot as the latest contestants of his challenge, each of the four's troubled faces sequentially slide into frame in vertical panels.

- Ditto for Naruto; well at least during the Chuunin arc.
- Similarly, One Piece has several protagonists with a strong tendency to overreact (with the exception of Robin), so this trope is a given.

- Happens several times an episode in Reborn!
- Given that Saint Beast has six protagonists and gets a lot of mileage out of Shōnen tropes, it was destined to happen.

- Episode 54 splits the screen in two for Pipin and Mami Bibir's shocked reaction every time Bambang and Melani is accused of being in a secret relationship. When Bambang shows his selfie with Melani to prove their relationship, the screen splits in four, adding Alexi and Juna's reactions.

- Parodied in one strip of The Way of the Metagamer.
- Another live-action example, Noob can indulge into this for shocking revelations.

- Also a common sight in Monster Buster Club. Including one in the Action-Hogging Opening.

- Gwen and Courtney know that either of them will be voted off in "Picnic At Hanging Dork". As Chris counts the votes, the screen gets diagonally split with the two girls at each side.

The fifth vote goes to Sierra, which causes a tie and leaves both girls stunned.
- During Chris's episode intro speech in "Runaway Model", the now exclusively male Toxic Rats are each given a quarter of the screen marked by a unique background color.

- Heather, Courtney, Duncan, Lightning, Scott, Mike, and Cameron are all part of a shredded reaction shot in "Heroes vs. Villains" when it is revealed that Alejandro was inside the Drama Machine all along. Each of them is differentiated with a unique color background and the composition highlights the reactions' level of importance. Heather, Alejandro's love interest and rival, is large and in the center. Courtney and Duncan, who've worked with Alejandro, are smaller and flank Heather. The Gen 2 cast members get the least space each and theirs are pushed to the side. With the unexplained exception of Lightning, none of them have much of a reaction because they have no history with Alejandro.
- Gwen's plea for the Villainous Vultures to work as a team in "Heroes vs. Villains" is met with deceitful agreement. As Heather, Jo, Duncan, Scott, Alejandro, and Lightning enter the confessional to voice their real thoughts, the next shot consists of close-ups of all seven Vultures in H-formation with Gwen in the middle. She's laughing amicably because she thinks she got through to the rest, the rest is laughing evilly against an Infernal Background.
- At the campfire ceremony in "Suckers Punched", Chris tells the contestants to hold their gasps until he's done with his announcements. Those are that the winners will choose which loser gets eliminated, that the losers will choose which winner goes to Boney Island, and that it's not yet time for the merge. When Chris gives permission to gasp, the contestants are framed in a reaction shot composed of four trapezoids between Scott and Alejandro, Cameron and Gwen and Courtney, Sierra and Duncan, and Zoey and Mike.
- Zoey, Mal, Gwen, Cameron, Heather, and Alejandro respond with a reaction shot composed of trapezoids upon beholding the Moats of Doom in "The Final Wreck-ening". Each of them is differentiated with a unique color background and the composition highlights the characters' relevance. Zoey and Mal, the two finalists, are depicted largest and take up a quarter of the shot each, while the other four, as helpers, have to do with less. As a couple, Alejandro and Heather get to share their own quarter and Cameron and Gwen have an eighth of the screen each.
- Can be seen in Wakfu, as with the above picture. Not surprising given the show's Animesque roots. Especially common during the Bontarian Gobbowl arc.
- We Bare Bears: In "Go Fish", the Bears have a three-way reaction to their fishing boat captain being Swallowed Whole by a giant goldfish.
