The Memory Fruit, in Metroid Prime 4: Beyond.
The Memory Fruit is an object in Metroid Prime 4: Beyond. They store the memories of the Lamorn priests that offered prayers at the Altar of Legacy. Placing Green Energy Crystal on the altar allows the memories stored within the Sacred Tree to bear the fruit.
Samus will receive the Memory Fruit along with the Legacy Suit after donating enough Green Energy Crystals. Possession of the fruit is required before storming the Chrono Tower and complete the game.
In the game's ending, Samus plants the Memory Fruit on Tanamaar, then relinquishes her Psychic Crystal into it, causing it to quickly sprout into a sapling.
