Anode Beetle

Anode Beetles are small black beetles with four yellow spots on their wing casings. Their name is due to them periodically producing electrical currents if another one is nearby. This creature is blissfully unaware of Pikmin, and if found alone, they are harmless; but if there is a partner nearby, they can produce an electrical barrier between them, making any nearby Pikmin subject to electrocution. As such, they are commonly found in groups of two or more. As swarming one while it is upright is ineffective, a Pikmin must be thrown on top of it to flip it over before it may be harmed. Purple Pikmin shockwaves can cause them to flip over even if not directly hit.

In Pikmin 251
The Anode Beetle appears in Pikmin 251. It functions the same way it does, except it now takes less time to regain invulnerability when flipped over.

In Pikmin Forever
In Pikmin Forever, Anode Beetles have improved graphics, now reflecting light colors, and new behaviors. They will usually gather in groups of three to five near sources of electricity, be it gates, wires, bulbs, or other electrical enemies. This enemy can be defeated much like it can in, as throwing a Pikmin on top of it will cause it to flip over. Throwing a Rock Pikmin onto it will cause its exoskeleton to shatter, exposing its backside which is much like the Armored Cannon Beetle's except yellow in color. An Anode Beetle in this state gives off a small yellow glow in dark areas, and is no longer vulnerable to non-Yellow Pikmin, as it gives off electricity constantly. They can generate electricity on their own in this state, but if it still has its wing casing, it needs a partner to generate a barrier.

In Pikmin: Dimensional Breach
In Pikmin: Dimensional Breach, Anode Beetles reappear, functionally identical to how they are in Pikmin Forever. Louie can recruit them with his special upgrade, and they can conduct electricity just like Yellow Pikmin. Their arcing electricity can also be used to attack enemies, but it will also shock any Pikmin who happen to also be following Louie.

In Pikmin: Ultimate Doom
The Anode Beetle, in Pikmin: Ultimate Doom, behaves mostly the same as it does in but may randomly electrify itself while flipped.
