Digimon life energy

Digimon life energy (デジモンの生命エネルギー, Dejimon no seimei enerugī) is the life force of a Digimon introduced in Digimon Savers. It has been represented as yellow luminous particles which disperse when a Digimon is permanently deleted, or on the verge of deletion.

Kurata Akihiro uses several Gizmon to absorb this energy from Digimon upon their deletion for the purpose of reviving Belphemon.
