The official term is "semi-clone". Semi-clones have several moves that are different from the original.

I.e. Wolf/Falco/Fox, Lucas/Ness, Luigi/Mario, Ganondorf/Falcon, etc.

Complete clones have only a few aesthetic changes as differences.

i.e. Roy/Lucina/Marth, Dark/Pit, Dr./Mario, etc.

(For further reading, see Clone.)
