Aeroblast has always been the signature move of Lugia. Sacred Fire used to be the signature move of Ho-oh, but it can be learned by Entei since Gen VI.
Machamp is the only Pokémon that can naturally learn Strength.
Z-Explosion does less damage than Explosion (but it doesn't kill you, so there's that).
Not a single Generation 1 Pokémon could learn Toxic via level up until ORAS, when Oddish and Gloom gained the ability to learn it at level 35 and 39 respectively.
Magearna is the only legendary that can't learn Toxic.
There are no moves with a priority of -2 in any generation, meaning all moves with a priority lower than -2 can gain 1 priority and all will be the same.
