Zebstrika should've been Dark/Electric. Being a dual-type would've been perfect for a Zebra based pokemon. And to add a second layer of meaning to it's design, it could've incorporate the "light and darkness" theme. Being part Dark would've also helped make it more stronger, since it's mainly a physical attacker.
>But why dark type? It's not evil.
Zebras are far more aggressive and a lot more dangerous than horses. Zebras have been known to kick each other to death, they will viciously bite any human that comes too close, and there are even many accounts of zebras killing lions.
