Manectric is a canine, quadrupedal Pokémon. Its body is mainly blue with a spiky, yellow mane on its head and yellow tufts of fur on its haunches and around its front feet. Its mane sticks straight up and has three points. It has a jagged upper jaw, red eyes, and holes on either side of its head that seem to be its ears. Each of its paws has three claws. Its blue, spike-like tail is bent at a sharp angle.
The yellow mane on Mega Manectric is considerably larger than its previous state. The center spike on its head has shifted, and now forms a large, tilted growth that extends over its snout and has a point on either end. The remaining two head spikes are thinner, longer, and have small, pointed bulbs in place of the earholes. The mane now extends down the length of Mega Manectric's body, forming four additional spikes. One of these spikes extends down past the Pokémon's chest and has points on both ends. The tufts of fur on its haunches are now blue and form more numerous, thinner points. While it retains the yellow tufts around its front feet, they now have two short spikes extending backward. Finally, Mega Manectric lacks the sharply angled tail of its previous state and now has red claws.
Manectric gathers electricity in its mane and then discharges it. This process creates thunderclouds, which it uses in battle. Since lightning falls in its vicinity, it is said to have been born from lightning and make its nest where lightning has struck. It lives in grasslands and savannas, and rarely appears in front of people. When it Mega Evolves, its speed is explosive and is equal to a lightning bolt. However, its body becomes filled with such an incredible amount of electricity that Manectric is unable to fully control it all, thereby irritating it.
