Chuck is the boss-NPC counterpart of the Cianwood City gym-leader.

As a multifunctional boss NPC, he is also a move-tutor of the Low Kick technique.

Boss rework 2019

Chuck 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.

Low Kick tutorship

In addition to his battlability as a boss NPC, he is also known for his tutorship over the Low Kick technique, imparting the move to any compatible Pokémon for PokémonDollar.png7,500 per tutee.

In order to access his tutorship, you will need to have challenged him at least once; irrespective of the outcome, it will be a gateway to follow-up dialogue, which includes tuteeship for this move; as such, it effectively prerequires satisfying the requirements to challenge him as noted above.

Challenging Chuck

Chuck resides in Saffron City, specifically in the Golds Gym premise.

Once interacted with, you have the option to initiate the battle with him contingent that there is no in-effect cooldown time and that you have satisfied all the battle requirements. If you lose, you must wait for 12 days to elapse before he is rechallengable. In case you should have a playing time under 100 hours, Chuck will give you a warning if you are really sure to fight him.

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 are initialized at level 20.

Reworked bosses such as Chuck 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.
