Poochyena in depth
The bite that opens Hoenn
In Ruby and Sapphire, it is the first wild Pokémon to do anything. It appears in the grass on Route 101 and attacks Professor Birch, and the player has to take their first partner out of the bag to get it off him: before choosing a companion, before the first battle against the rival, there is a grey hyena biting a scientist. It then appears on Routes 101, 102, and 103. Emerald greatly expands the list—from 101 to 104, 110, 116, 117, 120, 121, and 123, plus Petalburg Woods—so it accompanies the player through half the region without ceasing to be what it was on the first screen.
The anime repeated the scene. Several Poochyena debuted in “Get the Show on the Road!”, chasing the same Birch, this time separated from the group.
Pochi, the hyena, and the mask
The English name combines pooch, the colloquial term for a mutt, with hyena. The Japanese name, ポチエナ, does the same with its own material: Pochi is the default name for a dog in Japan, the equivalent of calling it Toby. The design reference is not the spotted hyena, the one seen in documentaries, but the smaller brown and striped hyena cubs with grey fur. The black mask covers its face and throat and continues onto its legs and belly, splitting the body into two tones and turning the head into a mask.
What you only see if you press B
Its level-up list reaches 44, but it evolves at 18. Everything below that line—Swagger at 19, Assurance at 22, Taunt at 28, Crunch at 31, Yawn at 34, Take Down at 36, Sucker Punch at 40, and Play Rough at 44—is only learned by a Poochyena whose evolution has been cancelled. What it sees before 18 is poorer than it looks: Tackle, Howl, Sand Attack, Bite at 10, Leer, and Roar. One 60-power attack and five status moves.
TMs cover part of the gap. Foul Play calculates damage using the opponent's Attack, so it hits harder than its 55 would suggest and is the only attack on the list that its stat sheet does not get in the way of. The three elemental fangs—Fire Fang, Thunder Fang, and Ice Fang, each with 65 power—and Psychic Fangs give it coverage it cannot maintain later. Double-Edge, at 120, is the highest number it will see, and with 35 HP the recoil takes away a large part of what it has left.
The first-route dog slot
Every generation puts a small mammal in the starting grass, usually in pairs. Poochyena shares the opening routes with Zigzagoon, which takes the collector's role while it gets to be the biter. The difference from the ones that came later is that, in its generation, it was also early access to a then-recent type: Dark had been in the games for one generation and appeared mostly late, in creatures such as Houndour, reserved for a specific point in Johto. Putting it on Route 101 was a decision later generations copied with their own animals, Nickit among them.
Its entry has not changed. Its base stats have remained intact since Generation III, and the only thing that moved was its ability list, with Rattled added as a hidden ability in later games.
