Limiters: Spiril's bacteria can only invade an opponent's body through direct physical contact as it is the only way he would be able to inject a high enough amount of bacteria for it to have any effect. His bacteria can also not dig through the skin, and can not invade the body unless there is an open wound or other possible entrance (nose, mouth, etc). His power to destroy bacteria is the one that drains the most of his energy and he will need to physical contact with the source of the bacteria to be able to use that power.
