The electrified mucus emitted by Mega Eelektross forms gelatinous, Eelektrik-like shapes at the end of each arm, collectively called “false Eelektrik” by scholars—the left one being “Eeleftrik” and the right one “Eerightrik.”

The false Eelektrik give Mega Eelektross improved stability when swimming. It can swim almost twice as fast as it could before Mega Evolving.

Most electricity that Mega Eelektross generates goes to the false Eelektrik flanking it. That electricity is powerful enough to stun and paralyze Pokémon as massive as Wailord.

When Mega Evolution wears off, the mucus that formed the false Eelektrik melts away and disappears. However, it can be preserved in its jelly-like form through freezing. Some people put this preserved mucus to new use in beauty regimens or strength training, though it’s not clear how much benefit it yields.
