Writers can also use the reactions of other characters to show Po's anger. For example, if Po is angry at Tigress for some reason, she might be taken aback because she's not used to seeing Po so angry. The other Furious Five members might try to calm him down, which also highlights the fact that his anger is out of the ordinary. By showing how his anger affects those around him, the writer can effectively portray Po's anger in the fanfiction.
Writers can show Po's anger through his physical actions. For example, his fists clenching tightly, his face turning red, and his body tensing up. Just like how he might look when facing a really tough opponent in the movies. They can also use his dialogue. Po might start stuttering a bit more when angry as he tries to get his words out while being overcome with emotion. For instance, he could say something like 'You... you can't just do that!'
One common scenario could be when Po's friends accidentally break his favorite training equipment. For example, if Tigress accidentally shatters his special wooden staff during a sparring session. Po might get angry because that staff has sentimental value to him, as it could have been a gift from Mr. Ping or something he found during his early days of training. Another scenario could be when there's a misunderstanding about food. Say someone takes the last dumpling that Po was really looking forward to. He loves food so much that this could easily make him angry in a fanfiction.
Writers can use strong body language descriptions. For instance, clenched fists, furrowed brows. They can also show his anger through his dialogue, like using short, sharp sentences. Another way is to describe his internal thoughts when he's angry, how he's seething inside but trying to control it.
The author can use strong dialogue. For instance, having Tony shout out angry words with a lot of force and passion. Words like 'I've had enough!' or 'You'll pay for this!' can quickly convey his anger. Also, the use of expletives (if appropriate for the rating of the fanfiction) can enhance the sense of his fury.
It could also be the sound of a monster or a demon that is lurking in the shadows. This creature might use the 'po po po' sound to disorient its victims. Say, it lives in an abandoned place and when someone enters, it starts making the 'po po po' sound to create fear and confusion before it attacks.
I'm not aware of such a specific fanfiction. However, in the Kung Fu Panda fandom, there are many creative fanfictions, but this particular theme might be quite rare or not in line with the general family - friendly nature of the original work.
The author can use physical cues. For example, Kuroko might clench his fists tightly, a rare display of emotion from him. His normally calm blue eyes could narrow and become more intense. Another way is through his dialogue. He could speak in a sharper tone than usual, with shorter, more forceful sentences.
A monster might be in a 'po po po scary story'. For example, a monster that has a strange way of communicating, like making the 'po po po' sound. It could lurk in the shadows and when it's close, it makes that noise to terrify its prey.
Once upon a time, in a small, old house, there was a strange noise that went 'po po po' every night. It was a doll. Its eyes glowed red in the dark and it moved on its own. Every time it made the 'po po po' sound, something bad would happen. One night, a girl woke up and saw the doll right next to her bed, making that terrifying 'po po po' sound.
In a small village, there was a well that made a 'po po po' sound. The villagers were afraid to go near it. One curious boy ignored the warnings. He peered into the well and heard the 'po po po' louder. Then, he saw a hand reaching out from the well. He tried to run but his feet were stuck. The 'po po po' was like the call of an evil entity from the depths of the well. Just as the hand was about to grab him, his friends pulled him away.
His anger often manifests physically. His muscles might bulge more than usual, and his hair could stand on end even more in his Super Saiyan forms. His ki, or energy, also becomes more visible and intense. It's like a red - hot aura surrounding him.
