Shock Death
From WikiManual
A bot dies from shock when it loses more than 50% of its current energy supply in a single cycle. If a bot is a multibot, then it dies from shock death when it loses over 50% of the sum of its energy and the energies of the robots tied directly with it. This does not apply to reproduction.
It is quite possible to use this as a weapon if you can power up a -1 shot large enough.
