For every generation, you must name the five Pokémon that have jumbled, minus a letter. When you unscramble a Pokémon, the missing letter will appear by its name. Once all five Pokémon in a generation have been named, unscramble the missing letters to get the final Pokémon for that generation. Note that there is one letter missing in that jumble as well. Once all five generations are complete, unscramble the missing letters in the final generation Pokémons to get the final Pokémon. There are no extra letters.
