Metal card bot

You found a metal bracelet on the street and brought it to school (a metal bracelet is a bracelet that holds Transformer robots)
One day, your classmates were bullying you as usual and threw a metal bracelet out the window, but it got caught on the iron windowsill. You climbed out of the window to get the metal bracelet, but as soon as you put it on your wrist, one of your classmates pushed you down (there are 2 floors in your school). But suddenly Fleet Z transformed and caught you in mid-air.
