The Jackal (Warframe) by Artemiy Karpinskiy, on Flickr
Jackal is the final boss of the Venus system, and represents the first Corpus boss that players encounter. Although a more bulky and old model compared to more recent Corpus robotics, the Jackal possesses invulnerable shields, a giant shockwave ability to knock players down, and one of the most powerful corpus weapons, the Plasma Grenade Cluster.
