Koichi is a boss NPC that is challengable to all qualifiable trainers in Saffron City Dojo.

It is homologous to the same Koichi character that presides over Saffron Dojo, interchanging with it when all qualifiers for its challengability are met upon entering the area.

Boss rework 2019

Koichi 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.

  • 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.

Challenging Koichi

Koichi stationarily resides in Saffron City Dojo, and he will be challengable contingent that he has no pending cooldown time, you have completed the Kanto League.

If the requirements are not satisfied, Koichi will be invisible while his non-boss counterpart is in his stead. The boss-NPC counterpart of Koichi will be visibilized upon entering the dojo with all the aforementioned conditional requirements met, interchanging with the non-boss counterpart in doing so. In case you should have a playing time under 100 hours, Koichi will give you a warning if you are really sure to fight him.

Should you lose to Koichi, he will be rechallengable after his 12-day-cooldown time has elapsed.

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 Koichi 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. George has some special rewards not every boss rewards such as Toxic Orb or Flame Orb.

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.
