How to make different stats and sprite for different genders

[Drayton]

Firstly, How do you make a sprite appear of opposing gender, say like I want to have a female pokemon with different sprite instead using default one also how to make a new stats for the opposite gender like meowstic for example in essential?

As for sprites, it's fairly easy to make a different sprite for the female - Looking at Pikachu, you can see that there's "025f" and "025fs". One's the sprite for the female, and the other's the sprite for the shiny female. The ones without letters would then become the sprites for the males.

As for the base stats and movesets, here's the code for the Gen VI Pack's Meowstic:

MultipleForms.register(:MEOWSTIC,{
"ability"=>proc{|pokemon|
   next if pokemon.gender==0              # Male Meowstic
   if pokemon.abilityflag && pokemon.abilityflag=2
     next getID(PBAbilities,:COMPETITIVE) # Female Meowstic
   end
},
"getMoveList"=>proc{|pokemon|
   next if pokemon.gender==0                                # Male Meowstic
   movelist=[]
   case pokemon.gender
     when 1 ; movelist=[[1,:STOREDPOWER],[1,:MEFIRST],[1,:MAGICALLEAF],[1,:SCRATCH],
                        [1,:LEER],[5,:COVET],[9,:CONFUSION],[13,:LIGHTSCREEN],
                        [17,:PSYBEAM],[19,:FAKEOUT],[25,:PSYSHOCK],[28,:CHARGEBEAM],
                        [31,:SHADOWBALL],[35,:EXTRASENSORY],[40,:PSYCHIC],
                        [43,:ROLEPLAY],[45,:SIGNALBEAM],[48,:SUCKERPUNCH],
                        [50,:FUTURESIGHT],[53,:STOREDPOWER]] # Female Meowstic 
   end
   for i in movelist
     i[1]=getConst(PBMoves,i[1])
   end
   next movelist[COLOR="Red"]
}, # any additional modules you add go after this line.[/COLOR]
})

This goes into the Pokemon_MultipleForms script. Note that it's just like any other form change - the difference is that instead of using pokemon.form, you use pokemon.gender, which is 0 for males and 1 for females.

Abilities and level-up moves aren't the only things you can edit for the different genders - that's just the only differences that Meowstic has. Examples of other modules you can add are:
Different types:

"type1"=>proc{|pokemon|
   next if pokemon.gender==0              # male
   next getID(PBTypes,:FIRE)  # female
},
"type2"=>proc{|pokemon|
   next if pokemon.gender==0              # male
   next getID(PBTypes,:FIRE)  # female
},

Base stats:

"getBaseStats"=>proc{|pokemon|
   next if pokemon.gender==0                 # male
   next [50, 180, 20, 150, 180, 20] # female
   # HP, Attack, Defense, Speed, SpAtk, SpDef
},

The EVs gained by defeating them:

"evYield"=>proc{|pokemon|
   next if pokemon.gender==0      # male
   next [0,2,0,0,1,0] # female
   # Like before: HP, Attack, Defense, Speed, SpAtk, SpDef
},

Weight (which actually has some strategic uses thanks to moves like Grass Knot) :

"weight"=>proc{|pokemon|
   next if pokemon.gender==0 # male
   next 6500               # female
},

The held items that they can have in the wild:

"wildHoldItems"=>proc{|pokemon|
   next if pokemon.gender==0                 # male
   next [0,getID(PBItems,:DEEPSEASCALE),0] # female
},

Height (though unlike weight this actually has no strategic use) :

"height"=>proc{|pokemon|
   next 65 if pokemon.gender==1  # female
   next
},
