Goku gets angry in the manga mainly when injustice is done or when his efforts to protect and save are challenged. His anger is often a response to a threat to the peace and safety of those he cares about and the world at large.
Often, Goku gets angry and goes Super Saiyan when he's facing an opponent who's way too powerful and has pushed him to his limits. Maybe that's the case here. Also, sometimes it's just to protect the Earth from a huge danger.
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.
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.
