Celebi was Generation 2's most difficult Pokemon to get and was basically the Johto version of Mew. You could either get Celebi from a direct event distribution or in Crystal by doing the special GS Ball sub-plot that was exclusive to the Japanese copies of the game until the VC re-release of Crystal.
