Wish the one of the MC's newcomer Pokemon is a ghost type Pokemon like Gastly, Duskull, Rotom or Honedge because most of the ghost type Pokemons can drill into the shadows of a person and act as another line for safety and they are also mischievous except for the Chandelure line because it is said in the Pokedex they can absorb souls. Gastly/Gengar (500 BS/600 BS Mega) probably shiny due to optimization because of it shiny Mega and Gigantamax form and my bias for the Gengar of the MC in I really don't want to be a Trainer. Duskull/Dusknoir (525 BS) also shiny because of the shiny coloring during Duskull and Dusclops period and also it can learn Gravity. Rotom (440-520 BS) because it can change form and it can go to the MC's phone. Lastly Honedge/Aegislash (520 BS) because of shiny coloring and its Stance Change ability.
