Sp;attack appears to be the Special Attack stat of a Pokemon. As SM said before, the base Attack and Special Attack of the FireRed version may be 180 (26 points higher than Mewtwo), its base Defense and Special Defense stats are a paltry 20 (70 points lower than Mewtwo). To put that in perspective, There are only six Pokemon in the game that suck more in Defense stat than FR Deoxys (Chansey, Blissey, Abra, Igglybuff, Elekid, and Pichu), and it is tied for the absolute worst Special Defense (with the likes of Igglybuff, Carvanha, Weedle, Caterpie, and Magikarp). That means you will get one shot with it. In other words, it sucks.
