A fruit from the planet Kaferia that Gary Mitchell creates out of nothing on barren Delta Vega to show Elizabeth Dehner the reach of his new powers.
The Kaferian apple is a fruit native to the planet Kaferia. It appears in Where No Man Has Gone Before, the second pilot of The Original Series, set in 2265.
Gary Mitchell, transformed by the energy barrier at the edge of the galaxy, escapes from confinement on the mining outpost of Delta Vega and takes the psychiatrist Elizabeth Dehner with him into the wilderness. There he wills a garden into being among the rocks, complete with a pool and a tree bearing Kaferian apples, and offers her the fruit as casually as a god in his own Eden.
The scene marks the point at which Mitchell stops thinking of himself as human. Kirk arrives soon afterwards with a phaser rifle, and Dehner, her own powers awakening, finally turns against Mitchell.
