Banshee

Banshees are synthetic creatures derived from asari and mutated by Reaper technology. Banshees were first introduced in Mass Effect 3. Frighteningly intelligent, the Banshee are advanced pressure units usually found leading a Reaper strike force.

Capabilities
Offensive

Banshees can also charge their enemies (similar to Biotic Charge). They also have the ability to grab people and subsequently impale them with their hands, resulting in instant death.

Defensive

Banshees possess substantial biotic powers, and can use their biotics to create barriers to protect allies. They can also use their charge ability to move quickly and unpredictably, which can make them very difficult to hit at range.
