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 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!'

In some 'Goku Gets Angry' fanfiction, a common scenario is when his friends are in danger. For example, if Vegeta is seriously injured by a powerful new enemy, Goku's anger flares up. He then enters a new and more powerful form to fight the foe. Another scenario could be when the Earth is threatened. Maybe a villain plans to destroy the planet, and Goku gets angry at the thought of his home and family being in jeopardy. This anger gives him the motivation to train harder and find a way to defeat the villain.
Obviously, Italy itself would be the main character. There could also be other European countries like France and Germany. They might be the ones causing Italy's anger, or they could be Italy's allies trying to calm it down.
One possible plot could be related to environmental issues. Italy is known for its beautiful landscapes. If other countries are not taking proper actions to combat climate change which is also affecting Italy's natural beauty, Italy could get angry. It might start its own initiatives and try to persuade other countries to follow suit, leading to a story full of challenges and cooperation.
