Pikadron is a large yellow monster with long antenna, extended fingers and toes, a green chest pattern, red eyes with a black outline. Beneath this, he possesses a more mechanical body featuring a v-shaped chest plate and red pincer claws.

As a being composed of electromagnetic waves, it is able to control electricity. It can release balls and beams of electricity from its mouth. It can emit electricity from it body. In its super form it can release seven beams of electricity from its chest and horns that are of higher voltage than its previous forms attacks.

Its body is impervious to damage except when it solidifies when attacking. It is also capable of absorbing energy to assume a stronger form.

Pikadron appears after the destruction of Bong, as the mechanical monster was just bait to lure out Great Mazinger. The Great could not damage Pikadron due to its light wave body and even with help from the Getter Robo G did not change much because of its ability to absorb energy and growing stronger. Tetsuya noticed that Pikadron could be damaged when solidified and pairing up for a final attack, they managed to destroy Pikadron.
