Top 5 Pokemon Berries of all time
#5 - Lum Berry
The Lum Berry is an all-round Status Condition fixer. It can be used by a Pokemon in battle or as a healing item by the trainer. If a Pokemon is burned, paralyzed, frozen, poisoned, or asleep, the Lum Berry will cure any of them and remove the condition.
#4 - Leppa Berry
The Leppa Berry is the Berry version of Elixirs and Ethers. Those items restore the Power Points, or PP, of a Pokemon's moves. These are super useful in situations when a Pokemon Center may not be an option. If held, when a move hits 0 PP, the Pokemon will restore it by 10 automatically. Otherwise, simply using it on them with raise a chosen move by that same 10 PP.
#3 - Damage Decreasing Berries
These Berries will be grouped into one. Passho, Chople, Occa, Yache, and Charti are the names of these Barries. They all reduce the damage received by certain types of moves. If a Pokemon holds the one that negates Water-type damage and is typically weak against Water, the respective Berry will be used in battle and lessen the damage one time allowing for some decent retaliation.
#2 - Silver Pinap Berry
This Berry from Pokemon GO is wonderful. It drastically increases the amount of Candy the Pokemon supplies to the trainer. These Candies are used to level up or even evolve Pokemon. The Silver Pinap Berry is a great way to ensure those last few Candies are snagged for that sweet evolution.
#1 - Sitrus Berry
The Sitrus Berry is one of the most common Berries used in Pokemon. They are the favorite of NPCs, Gym Leaders, and competitive battlers. A Sitrus Berry will heal 25% of the Pokemon's max HP in battle. Being able to heal in a battle where using items isn't normally allowed or wasting a turn on it could be costly is invaluable.
