Pikachu Libre is a reward for reaching Rank 10 in the GO Battle League Season 4. They're the same rewards as Season 3, but the way of climbing the League has some changes. At the end of the day, you just have to grind through the rankings until you're the very best.
Pikachu Libre Pokémon GO: How to Get
Getting to Rank 9 is easy enough; you just need to win games. Losses aren't counted against you, but you need to win often to advance. This has been changed since last season and is overall slightly easier.
Reaching Rank 10 remains unchanged. You'll have to get a rating of 3,000 to be qualified for Rank 10. You'll earn Pikachu Libre finally, so you it's mostly a matter of grinding battles for it.
Pikachu Libre itself is a special version of Pikachu that knows the Fighting-type move Flying Press. The Battle League is the only way to get Pikachu Libre, but it has been stated earlier that Pikachu Libre will appear in lower ranks in future seasons.
For now, Pikachu Libre is still a Rank 10 exclusive, so gather your best Pokémon and take on Season 4.
