Boltund's a slew of wasted opportunities. During prerelease I was hoping for Yamper to evolve to an Electric/Fairy
Cu Sith. But nope, it evolves into a pure Electric-type based on an ordinary dog with no signs of a fae theme. Its design also reminds me of a complaint people have with the Lilipup line - sure they're very realistic, but Herdier and Stoutland are more than capable of pulling their weight throughout the game.
Bolthund:
69/
90/60/
90/60/
121
Herdier: 65/80/
65/35/
65/60
Herdier can take hits better than Boltund, and its attack stat is only 10 points weaker. .
