Lambda Power

The Lambda Power (ラムダ・パワー) appeared in Act 60 of the manga and Sailor Moon Cosmos. The exact nature of this power was never explicitly explained, but it was stated to be the power of rebirth, and appeared to occur when all of the galaxy's Sailor Crystals were combined into one power and focused with the Cosmos Crystal. Through the use of this power, all of the Sailor Senshi killed in the fight against Sailor Galaxia were sent to be reborn.
