Alright thanks. Also, another simple question for a simple answer. Can Sand Attack hit Flying-type Pokemon? I've never really seen the outcome of such an attack, and I know it's Ground-type so I assume it's going to miss it, but I've never done it in R/B/Y to see if it hits.

Actually sand attack does hit flying types. Similarly, confuse ray and night shade will hit normal types, counter and seismic toss will hit ghosts etc.

The only non damaging attack that will fail because of type in RBY that I can think of is thunderwave..

Edit: Instead of taking up another post, might as well ask it in this same post since my question above hasn't been answered yet, so this way I'll hopefully get my two questions answered. Anyways, onto my 2nd question. If you score a Critical Hit, does the Critical Hit negate or add STAB if a STAB move occurs?

Here is the scenario: I have a Persian with Slash. My opponent has, oh lets say a Chansey (the Chansey doesn't really matter, I'm just randomly throwing it in there so my opponent has a Pokemon for you to image being fought against). My Persian uses Slash, and since my Speed stat is a lot of higher than my opponents Pokemon I have a higher success rate of a Critical Hit %. So since stat-up moves like Swords Dancing up negates the CH of Slash, does this occur with STAB? Since Persian is Normal-type and so is Slash it gets the STAB 1.5 bonus, but will it add to Slash's power with a CH or will it just be a CH with no STAB damage added? Also, how much more damage does a CH do? Is there a set percentage/decimal number for the damage? Like how STAB is always x1.5+ damage. Would a Critical Hit be just as much damage as a STAB hit?

you still get STAB bonus (and super effective bonuses) with Critical Hits. Critical hits roughly double the damage you cause. It actually doubles your level in the damage formula, so you usually get slightly under double damage.

Have a nice day.
