Psions

Invasive Species are a new category of Aragami first introduced in God Eater 2. They are heavily modified versions of other existing Aragami that possess new skills, known as "Blood abilities".

Blood ability
Kabbala Kabbala's "Oracle Emission" boosts the Oracle cells of both allies and enemies, inducing Enraged mode on other Aragami but also providing any God Eaters in the vicinity with a level 3 Burst.

Blood ability
Magatsu Kyuubi's infamous "Black Hole" ability allows it to create several Orbs that reduce the maximum HP of any God Eater in a large area surrounding them.

Blood ability
Marduk's "Pulsating" ability disables any God Arc in the vicinity; only the members of Blood are immune to the effect. Non-Blood God Eaters who have awakened Blood Arts are also immune.

The "Pulsating" ability also attracts every other Aragami in the field to the Marduk's position.

Blood ability
Nyx Alpha's "Revival" ability enables it to heal any wounded Aragami nearby, just like God Eaters do with their recovery bullets.

Also worth mentioning is that, whether related to its Blood ability or not, Nyx Alpha is completely immune to melee attacks of any kind, and can only be harmed with long range attacks (bullets, Impulse Edge...).

Blood ability
Spartacus' "Oracle Absorption" ability allows it to absorb nearby Oracle Cells to increase its own power up to three times, leeching other Aragami's life in the process.

Blood ability
Yan Zhi's "Summoning" ability allows it to periodically summon minor, Ogretail-like Aragami called Yan Zhi to assist it in combat.

It also enables it to make other Aragami to focus on a given target by "Marking" them.
