Detonators, also known as Wave Weapons, are a series of weapons created by Relius Clover.
The Detonator series of weapons were made by Relius during the Ikaruga Civil War; the only one that has been shown is the Fluctus Redactum: Ignis. They are based off the Artificial Causality Phenomenon Weapons that were constructed by Kokonoe, but have their own modifications added by Relius himself. Their power is comparable to the Nox Nyctores - Ignis' power is comparable to that of the Deus Machina: Nirvana of which she was based off. 
According to Relius, a strong soul is needed for one to be used as material for a Detonator. Ignis Clover's soul was strong enough, and it is stated that Makoto Nanaya has a soul which could easily fulfil the strength required.  Detonators other than Ignis exist, with there being four others, including prototypes.
Weapons created by Relius Clover based off of the Phenomena Weapons. Their basic construction doesn't differ from Phenomena Weapons, but he's added his own modifications as well, so their true power is unknown.
The only confirmed Wave Weapon is 'Ignis' in the possession of Relius, but there are least four including prototypes. It's also called a 'Detonator.'
