 A name can be up to 12 characters long. Note that the trainer class and individual name will get printed on one line in phrases like "PARASOL LADY SUE wants to battle!" so make sure the whole phrase will fit in 18 characters.

 The four numbers define, in order, the Attack, Defense, Speed, and Special DVs for all the trainer class's Pokémon. Each DV can be from 0 to 15. (Remember, in Gen 2 there was one DV for both Special Attack and Special Defense; and bits from all four DVs were combined to calculate HP.)
 
 Female trainer classes tend to have low Attack DVs so that their Pokémon will usually be female (since gender in Gen 2 was determined by the Attack and Speed DVs, primarily Attack). Gym Leaders are mostly an exception to this rule.
 
-You may also want to choose DVs that give some important Parasol Lady the right Hidden Power type, if that's relevant. Or follow [this tutorial](Allow-more-trainer-parties,-with-individual-DVs,-stat-experience,-and-nicknames) to give individual trainers unique DVs (as well as stat experience and nicknames!).

 We have to use `dba_pic` here instead of a standard `dba`—declaring the bank and address of `ParasolLadyPic`—because of [this design flaw](../blob/master/docs/design_flaws.md#pic-banks-are-offset-by-pics_fix). I strongly recommend removing the whole `FixPicBank` routine from [engine/gfx/load_pics.asm](../blob/master/engine/gfx/load_pics.asm), including all four calls to it in that file, and just using `dba` here; then you'll be able to `INCBIN` sprites in arbitrary banks.

 Valid sprites are in [constants/sprite_constants.asm](../blob/master/constants/sprite_constants.asm). They're for the 16x16 overworld sprites, not the 56x56 battle sprites. Adding a custom sprite is beyond the scope of this tutorial.
