Many characters share similar moves but are not clones as well, in Smash 64 Captain Falcon and Samus share neutral aerials, down smashes, floor attacks, forward tilts, up tilts, and dash attacks, but have their own unique physics and moves as well to a point where they are not considered to be semi-clones.
Smash even has it's own unique term for the way clones change between releases of sequels called "Luigification" referring to how Luigi started as a full clone of Mario in Smash 64 but has been decloned in each additional installment. Several clones have been "Luigified" over the franchise as well like Ganondorf and Falco.
