>>46484130Lucario looks like a stupid human Egyptian anubis dog, and they shilled it hard as fuck back then, so that's how they succeeded. Dogfuckers and furfags everywhere instantly latched onto Lucario. It ticks all the right FurAffinity boxes: Large, comical dog snout, bipedal, colorful fur, chest fur and tuffs of hair, and random spikes. It was the perfectly engineered furfag Pokemon.
Zoroark fails because it looks considerably less human, it's a bit anthro but not enough, and the color scheme isn't as bright and inviting. It's also based on a kitsune with a clown makeup and a giant frazzled ponytail. They tried shillong it again but the design was so weak compared to Lucario that they took notice of the overt shilling and began to feel repelled by it even more.
Zeraora is just a shit design, period. It's what you'd fine on FurAffinity like Lucario, sure, but it would be like the kindergarten crap buried deep beneath the search archives, not a popular front page runner like Lucario.
