"I see you have grown stronger since our gym battle, but so have I. Let me challenge you; I want to test how much both of us have improved!"


Erika is the gym-leader boss NPC of the eponymous Celadon City gym-leader.

As a multifunctional NPC, it is also sought-out as the official Giga Drain-tutor in addition to its conventional boss-NPC functions.

Boss rework 2019

Erika was part of the Boss rework in 2019 and was updated at the 10th January 2019. The boss rework was issued and is still ongoing to improve the boss NPC's in general. All reworked bosses are coded in Python and not in Xanascript anymore, which gives new opportunities. Reworked bosses can now have held items as well. One of the biggest benefits is, that the Python script sees when if the server crashed in order to not count a lose in case the player fought against the boss while the server crashed. In such a case the player can simply re-fight the boss.

The boss rework implies a challenge for players on any experience level who do enjoy doing bosses because of the three difficulty level every not story related boss has, which ensures that bosses are challengable for newer players and also be a chellange for those who have a high Pokémon knowledge. Boss teams are decisively reworked and only contain level 100 Pokémon. EVs and hold items do vary among other things - also depending on the difficulty level. Boss Pokémon are not restricted to only using one move when holding a choice item.

  • Easy: bosses have no EVs and no hold items; as well as a weakened moveset. Consecutive win rewards are also not available.
  • Medium: bosses have 252 EVs in each stat and hold items.
  • Hard: bosses have 400 EVs in each stat and hold items. Furthermore, the player is not allowed to use in-battle items such as Revives.

Giga Drain tutorship

Erika will also teach the Giga Drain technique to any compatible Pokémon tutee for PokémonDollar.png7,500 per transaction.

Tuteeship does not require you to have previously defeated her.

Challenging Erika

Erika resides in the environs of Viridian Maze, where she exists on the pretext of planting a bush.

Because of the area's lightless obscurity, you are strongly recommended to bring a Flash-wielding Pokémon or a Flashlight on-hand to illuminate the area for navigational purposes; this can be obtained early on as HM02 in a Route 2 stophouse.

In the sinuous maze, Erika can be found in the north section of the west half of the maze.

Once interacted with, you have the option to initiate the battle with her (in addition to her Giga Drain tutorship) contingent that there is no in-effect cooldown time. If you lose, you must wait for 12 days to elapse before she is rechallengable.

The standard subsets of rewards will be randomized and rewarded each time; however, upon defeating him three-consecutive times, you will get a extra reward on the difficulty level Medium and Hard while Hard gives slightly better rewards.

There is no shiny counterpart of Pokémon rewarded from the randomized prizeset; only the selectable prizes have one, which is 1/4,096 in fractional notation (0.0244%, in percental notation).

All rewarded Pokémon will be initialized at level 20.

Reworked bosses such as Erika have rewards depending on the difficulty level you beat them. As harder the difficulty as more valuable is the reward normally. The exact reward is random generated based on a list of possible rewards and contains at least a money reward. There are three difficulty level: Easy, Medium and Hard. For extra rewards, the Medium and Hard level have a three-time win streak.

Tier 1: A random amount of common items which depends on the boss, like Focus Sashes, Weakness Policies, Air Balloons,Lum Berries or Sitrus Berries.

Tier 2: A random amount of more valuable items, mixed with some high valuable rewards depending on the boss, like PP Up's, Rare Candies, Small Train Ticket or Corphish.

Tier 3: Rare Pokémon depending on the boss, like Gible, Dratini, Bunnelby or Scyther.

Easy: 85% chance for tier 1, 10% for tier 2 and 5% for tier 3 rewards, 5-10k money reward.

Medium: 80% chance for tier 1, 10% for tier 2 and 10% for tier 3 rewards, 12-30k money reward, +2 PvE Coins.

Hard: 60% chance for tier 1, 25% for tier 2 and 15% for tier 3 rewards, 20-40k money reward, +4 PvE Coins.

The possible rewarded Pokémon on the hard mode are considered as slightly more valuable than those you may get on the Medium mode.
