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.

Togedemaru is the cute electric rodent Pokemon of Gen 7 (in the same vein as Pachirisu, Emolga, Dedenne etc). It’s replacing Dedenne as a Pokeball Pokemon in Smash Ultimate.
In the anime, Mamane/Sophocles has a Togedemaru. She seems to like Ash’s Pikachu a lot, often snuggling up to him despite being so spiky. She helps as Sophocles night light.
Its typing of Electric/Steel is pretty good; it’s 4x weak to Ground (but it does learn Magnet Rise by level up), but has a lot of resistances. Being a Pokemon that doesn’t evolve, it doesn’t have very high base stats, but it does have a pretty good stat distribution, having decent Attack and Speed. It has a signature move in Zing Zap, which is a base 80 Electric physical move that has a chance to flinch (basically the electric version of Iron Head)
