I have been working on website (un)official Pokemon fan website and as part of this project we need to create pages with Pokemon data. I found Pokéapi which is a Pokémon RESTful API. Pokéapi have all the data (and even more) that what I need in order to generate my nodes. So, I wrote a module that is going to take data from Pokéapi and generate into nodes. I decide to upload that module into Drupal.org just in case someone was to build another Pokemon website.
Initially, I wrote a Drupal 7 module, but since this is a very simple module I decide to port this module to a Drupal 8 module. The D8 version does not require any extra contrib module thanks to the CMI. Here is the project page: https://www.drupal.org/project/pokeapi
