Aipom and Ambipom are Normal-type Pokémon, first found in the Cobalt Coastlands. While not impressive at first glance, Ambipom has enough Speed and Attack to make it a Pokémon worth adding to your collection. Here is the best nature for Aipom and Ambipom in Pokémon Legends: Arceus.
Ambipom, as mentioned, has a base Attack of 100 and a base Speed of 115. His other stats are middling at best, with 66 for his Defense and Special Defense, and 75 for his HP. You should really focus on letting Ambipom in and dealing some damage, but knowing that it will double when hit with almost any attack. Therefore, Ambipom’s best natures are either Adamant or Jolly, with Adamant being slightly more valuable due to the Agile/Strong Style system.
Unfortunately, Ambipom’s move pool leaves a lot to be desired. Your options are Iron Tail, Fire/Thunder/Ice Punches, Shadow Claw, Double Edge, and Double Hit. The rest of Ambipom’s moves are Special Attacks, and unfortunately they aren’t worth much due to Ambipom’s low base 60 Special Attack stat. There are several normal types that beat Ambipom in damage and survivability, so unless you’re a die-hard fan, you might want to replace Ambipom at the earliest opportunity.
