Carom (キャロム) is a floating security spherical Mechaniloid enemy from the Mega Man ZX series. It has an impenetrable outer shell that can split into four parts. In Mega Man ZX, its shell is blue with a red stripe on each shell segment. It attacks by opening its shell horizontally or vertically to reveal a glowing yellow core and firing two shots up and down or left and right, depending on how the shell opened. It can only be harmed while the shell is open. It explodes upon defeat, harming the player if he/she is in the blast range. In Mega Man ZX Advent, the only change is that the blue on the shell has become green, and it does not always fire upon opening.
Using Model F's knuckle busters to punch it, sends the Carom flying around bouncing on the walls until it explodes.
