In Pikmin: Sinister Incinerator
Voltage spires are tall structures in Pikmin: Sinister Incinerator that were erected in Penumbra Plains, particularly around the G-Base to protect it from intruders. They are made of sturdy metal with wires running through the interior portions and electricity crackling at the top. Bolts of this electricity are fired at Pikmin or leaders that draw near. To destroy a voltage spire, Yellow Pikmin must be directed towards it; they will automatically climb to the top and destroy the conduit, causing an explosion at the base of the structure and the structure's subsequent collapse.
