Is this Pokemon viable?

Ononokus

One of the most proclaimed Pokemon out of Generation 5, Ononokusu is glaring at us with that badass looking axe face and we just can't look away. This thing boasts a monster 147 base attack stat, the second among non-legendaries behind only Rampardos. That also means that it has a STAB Outrage on par with Rayquaza.

We've all seen what all the previous dragons have been able to do, specifically Garchomp and Salamence. How will our Axeface reshape the metagame? In a land where 130+ base stats were given away like candy on Halloween, has GameFreak gone too far?

Is Ononokus a viable Pokemon? Hell yes!
