Batterybot
From WikiManual
A batterybot is a type of bot that uses a veggy as a portable 'power source', draining its energy but keeping it alive. It could be regarded as a special type of sharefeeder.
Batterybots have acess to a nearly unlimited energy source and can perform feats that would be nearly impossible to a regular bot such as storing up huge amounts of poison, venom, slime etc. and using very powerful shots.
