The siphon grenade is an item and weapon in Doom (2016) which can only be used by the Doom marine, as it depends upon the unique abilities of the Praetor suit to absorb and utilize Argent energy. It functions on the basis of alternately charged Argent energy fields, creating a positive charge on the user's suit and exploding with a negatively charged field. The resulting differential creates an attractive Argent field that pulls plasma from any demons caught in the blast radius, feeding it back to the marine as energy which can heal him.
