KillPlant (キルプラント,KiruPuranto) is a virus from the Mega Man Battle Network series. They are stationary plant-type viruses that spit out seeds. If the seed does not land on a target, it stays on the panel. A few seconds later, the seed turns into a target-seeking wooden spike.
KillPlants are red-orange with a light-green base.
Tree Bomb, known as Forest Bomb (フォレストボム,Forest Bomb) in Japan, is the Battle Chip family from KillPlant viruses. The user throws a seed three squares ahead. After a while, it grows into a Wood Tower and moves forward. The seed will automatically change when hit with an Aqua attack.
