Togedemaru

Sun: The spiny fur on its back is normally at rest. When this Pokémon becomes agitated, its fur stands on end and stabs into its attackers.

Moon: The long hairs on its back act as lightning rods. The bolts of lightning it attracts are stored as energy in its electric sac.

Ultra Sun: When it’s surprised or agitated, the 14 fur spikes on its back will stand up involuntarily.

Ultra Moon: Its capacity to produce electricity is somewhat limited, so it gets charged up by letting lightning strike it!

Sword: With the long hairs on its back, this Pokémon takes in electricity from other electric Pokémon. It stores what it absorbs in an electric sac.

Shield: When it’s in trouble, it curls up into a ball, makes its fur spikes stand on end, and then discharges electricity indiscriminately.
