They would bite humans and cause harm. It was reported that Liu Yongjun, a senior engineer at the Forest Pests Control and Inspection Station in Liangshan Prefecture, had been fighting Red Fire Ants for eight years. However, despite many years of effort, the Red Fire Ants were not completely eradicated. Instead, they spread to other places in Liangshan Prefecture. Currently, Red Fire Ants had also appeared in Dechang, Huili, and Ningnan in Liangshan Prefecture. Nevertheless, people generally believed that the battle was defensible and controllable, which meant that humans could take measures to prevent and control the spread of the Red Fire Ants.

If the MHA characters were to react to a Mastermind fanfiction, some would be more accepting than others. Characters like Ochaco might find it really exciting. She's a fan of the heroes herself, so seeing different takes in fanfiction would be like getting a new perspective on the MHA world. However, characters like Shoto, who are more reserved, might be a bit hesitant. He might need some time to process what he's reading. But overall, it would be a very interesting scenario as it would show how the characters view different interpretations of their world.
