Mew Move Tutor

The Mew Move Tutor is a special NPC that appears in Pokémon XD: Gale of Darkness. His sole purpose is to teach moves to Mew, however instead of asking the player to choose the moves directly, he has them answer several questions to determine a set of 4 moves given.

Overview

The Move Tutor appears at Mt. Battle if the player has a Mew in their party. Since Mew does not natively appear in Gale of Darkness, it must be transferred in via Link Cable from a different Generation III game.

Speaking to the NPC and answering his questions is free, however once the player accepts the proposed moveset, they are charged 5,000 Poké Coupons.

The NPC asks a total of 5 questions, and each response the player chooses affects a set of hidden score values. At the end of the sequence, the NPC then proposes a set of 4 moves based on these score values. If this move set is accepted, then the player's Mew will be taught the entire set, overwriting their currently-owned moves.

A pool of 100 moves are available through this tutor - this includes all moves that Mew could learn in Generation III from level up, TMs, HMs, and other Move Tutors, with an additional 6 moves exclusively available through this tutor. However, due to how the move set algorithm works, it is only possible to have one move from the exclusive set at a time.

Questions

When a question is asked, only 2 of the possible responses are offered to the player, even if the question has 3 or more possible responses.

Each response chosen adjusts three values: attack, strategy, and risk. All three values start at 0.

If a response has a range instead of a single number (example: "-1 to 3"), then that response chooses a random integer within that range (example: -1, 0, 1, 2, or 3), with all integers having an equal chance to be selected.

Question 1

Question: "What are Pokémon to you?"

Response	Attack	Strategy	Risk
Collectibles	-	+1 to +3	-
Friends	-	+1	-
Treasures	-	-3 to -1	-

Question 2

Question: "How would you like your MEW to be?"

Response	Attack	Strategy	Risk
A strong MEW	+2	-	-
A kind MEW	-2	-	-
A weird MEW	-	-	+3
You decide	-	-	-3 to +3

Question 3

Question: "What kind of TRAINER are you?"

Response	Attack	Strategy	Risk
Strike first to win	+2	-	-
All-out attack	+1 to +3	-	-
No giving up to the end	-	+1 to +3	-
A loss is a win	(See below)

Choosing "A loss is a win" has two possible outcomes, each with a 50% chance to occur:

Outcome	Attack	Strategy	Risk
Outcome A	-2	-	-
Outcome B	-	-1 to +3	-

Move set determination

Category

At the end of the questionnaire, the NPC will select one of 6 categories based on the how the attack, strategy, and risk values compare to each other.

Highest value	Second-highest value	Lowest value	Notes	Category
Strategy	Attack & Risk		-	Combo
Risk	Attack & Strategy		-	Risky
Attack	Strategy & Risk		-	Offensive
Attack	Strategy	Risk	Risk < 1	Reliable
Attack = Risk		Strategy	-	Offensive
Attack = Strategy		Risk	-	Reliable
Strategy = Risk		Attack	-	Defensive
Attack = Strategy = Risk			-	Random

Subcategory

After choosing a category, the NPC will choose a subcategory.

• If the category chosen was "Combo", then the subcategory chosen will depend on the attack, strategy, and risk values.
• If any other category was chosen, the subcategories are instead chosen by random chance.

Within each subcategory is a set of templates for the 4-move set that the NPC will propose. The NPC will choose one of these templates at random.

Within each template, each move slot of the set has certain rules applied to it:

• A fixed slot can only contain certain moves.
• A flagged slot can only contain moves that have (or don't have) a certain flag.

The following flags are possible:

• SPECIAL - special attacks.
• PHYSICAL - physical attacks.
• CONSISTENT - moves with 100% accuracy and no drawback.
• PUNCH - punching moves.
• NONE - moves with no flags.

Additionally, the following groups describe available moves:

• INCONSISTENT - any move without the CONSISTENT flag (including moves with NONE).
• OFFENSIVE - any move with the PHYSICAL or SPECIAL flags.
• ANY - any move in the pool, regardless of flags.

Note that moves which are exclusive to this tutor can only appear in fixed slots.
