Trivia

 * All Pokémon that require an evolution item to evolve cannot be either caught in the wild, hatched from an egg nor be a Raid Boss in the gym and the only way to acquire them is the evolution.
 * Historically, in the Pokémon game core-series, the following conditions described below will take place when one of these items are given to a Pokémon to hold:
 * Pokémon capable of holding either a Dragon Scale, King's Rock or Metal Coat will evolve when traded.
 * Pokémon capable of holding either a Sun Stone or Up-Grade will evolve when leveled-up.
 * On the official support page for Pokémon GO, Deepsea Scale and Deepsea Tooth are mentioned.
 * In the main series games, these items are required to evolve Clamperl into either Huntail or Gorebyss respectively.
