Memory Head is a trio of Amalgamate found in the True Lab. It was accidentally created by Alphys as an attempt to make a monster's soul last after death by injecting Determination inside comatose monsters. This action had the unexpected result of bringing said monsters to life, albeit for a short time. The Determination inside the body of these monsters soon caused their magic-based bodies to melt, fusing them into beings called "Amalgamates".

Unlike other Amalgamates, it is unknown what composes Memory Head. It doesn't appear at the Epilogue of the route and is not mentioned by other characters.
