Protecto

Protecto is a virus from the Mega Man Battle Network series. They never appear alone, and they all need to be destroyed at the same time in one hit. Otherwise, their HP restores back to their original amounts. This is where PAs come in handy. There is a countdown timer on this virus starting at 10. When the timer reaches 0, the virus attacks. After the attack, the countdown resets back to 10 and starts over.
