Illegal move combinations

Sprite	Name	Moves	Game	Notes
	Psychic Mason's Blastoise	Mirror Coat and Haze	Pokémon Stadium 2	This is the eighth Trainer in Poké Cup Ultra Ball R-2. While Blastoise can learn these moves by breeding, it cannot learn both simultaneously, as there is no Pokémon in the same Egg group as Blastoise that can learn both of these moves.
	Lt. Surge's Raichu	Surf and Reversal	Pokémon Stadium 2	Lt. Surge has this Raichu when fighting him in R-2. While Raichu can learn both of these moves individually, there is no way for it to legally know both moves simultaneously. Surf can only be obtained as a special move as a Pikachu in Pokémon Stadium, while Reversal can only be obtained by breeding.
	Bruno's Exeggutor	AncientPower and Explosion	Pokémon Stadium 2	While Exeggutor can learn both of these moves individually, there is no way for it to legally know both moves simultaneously. AncientPower is an Egg move that does not exist in Generation I, while Explosion is a Generation I TM.
	Walter's Parasect	Bullet Seed and Leech Seed	Pokémon Black and White Versions 2	Bullet Seed was a TM available to Parasect in Generations III and IV, but Leech Seed is only available to Parasect by breeding beginning in Generation V.
