>>22074143Well, they and Keldeo are based on D'Artagnan and The Three Musketeers, which is one of my absolute favourite books, plus I think they all have very interesting designs and backstory. Up until they were revealed, nearly all legendaries in the franchise were either allies or neutral to humans, so it was interesting to see legendaries that not only opposed humans but waged war against them too.
Plus, Terrakion = bara, Virizion = femboy, Keldeo = qt kelpie, Cobalion = outright awesome. Who could resist such a good combination?
