Delibird in depth
The tail is the sack
The name is the same in English and Japanese, and it comes from the same place: delivery plus bird, the delivery bird, デリバード in katakana. The reference is Santa Claus, and the design carries it out without hiding a thing — the red and white, the sack on its back, the presents coming out of it. The only thing that changes from the myth is who receives them: not children who have been good, but people lost in the mountains.
Comparing it with Farfetch’d is almost mandatory. Two one-stage species, each built around a visual joke and stats that go nowhere. The difference is what came later: Farfetch’d eventually received an evolution in Generation VIII, while Delibird is still exactly where they left it in 1999.
Present, the package that sometimes heals the opponent
Present is a physical Normal-type move with 90% accuracy and 15 PP, and its effect is rolled on every use: 40% of the time it hits with 40 power, 30% with 80, 10% with 120, and the remaining 20% heals the target by a quarter of its maximum HP. One time in five, the attack is a literal gift to the opposing side.
In Gold and Silver, the calculation was also broken: the game replaced the level, Attack and Defense with the index numbers of the types involved, producing results that made no sense. Crystal and Stadium 2 fixed it. Since Generation III, if the target is at full HP, the move does absolutely nothing.
Until Generation IX, it was the only Pokémon that learned Present by levelling up. In Scarlet and Violet, that stopped being true: Iron Bundle, its paradox counterpart, also has it from level 1. Other species have had it as an egg move for a long time, including Chansey, Marill and Togepi.
Everything good comes by machine
Its level-up learnset in Scarlet and Violet has two entries. Two: Present at 1 and Drill Peck at 25. Everything else — Blizzard, Ice Beam, Brave Bird, Focus Punch, Foul Play, Gunk Shot — comes by TM, and that is the cruel part of the matter: the catalogue of machines it can use belongs to a serious attacker, mounted on 55 Attack and 65 Special Attack that will not get any of those moves’ power off the ground.
For anyone using it in a normal playthrough, the sensible option is to forget Present and rely on Blizzard or Air Slash, using its 75 Speed to come in, set Spikes or Tailwind, and leave. A real offensive Ice type such as Weavile gets done in one turn with what takes three here.
In the anime, it has been seen in Team Rocket’s hands, which is more or less where a delivery Pokémon belongs when its package goes wrong one time in five.
