Ah yes. You must be speaking of Rashbeak! Quite frankly, I’m entertained by them. Pokémon in musical acts are nothing new, but very rarely is one allowed to be the singer. On the other hand, given the number of incidents involving wigglytuff acid rock bands in the 60s, I suppose it’s perfectly understandable.
As for whether or not Rashbeak is better or worse than TOGEPIMETAL, I admit I lean more towards TOGEPIMETAL. The idea of an all-lass death metal band amuses me, I admit.
Finally, concerning your question about Vikings and chatot, absolutely. I have also been told clefairy are suitable companions as well. They are, after all, known within certain folklore as “fearsome and almighty dragon-eaters.”
