Violet Parr's test (Pixiv Fanbox)

There are superheroes but there are also supervillains, the best at infiltrating are certainly those who can become invisible. So the government decided to use the heroes to test traps in case of enemy attacks. Violet was chosen, became invisible, and tried to infiltrate the military base but she was immediately blocked by the trap, obviously the trap could not be lethal and should not have inflicted damage on the girl. So spikes came out of the trap, the girl's shoes were removed and her spikes began to scrape hard and vibrate against the soles of violet's feet forcing her to laugh loudly and lose control so that she stopped being Invisible. His brother Flash teased Violet for a month, telling her that even a normal human could beat her with a couple of feathers.
