A black ops team formed in secret by the United Front during the Annihilation Wars. Comprised of the best soldiers and assassins in the galaxy, the team was created to perform tactical strikes by infiltrating the enemy and gathering information as well as taking out the command structure and key targets or anything that poses a greater threat. Currently the team has been sanctioned by the Galactic Council but remains independent and autonomous. When not at war the team hunt down criminals, pirates and rogue factions. The Stalkers base is an experimental Shi'ar stealth cruiser called the Spear-Tip.
