Shiva first appeared in Wolverine vol, 2. # 50.
Shiva is a task specific computer program that inhabits the Shiva robots each time learning and adapting from its previous battles with its opponents. It was created with a finite number, the exact number is unknown. It's primary mission is to be the Weapon X enforcer and to track and terminate any Weapon X operative that leaves the program. It has a list of names of each Weapon X member in a priority sequence.
Powers and Abilities
As a robot Shiva possesses enhanced response time analytical abilities and targeting huds, while also possessing detailed files of its targets allowing it to be an efficient fighter and tracker. Durability
The Shiva robot's outer shell is partially adamantium-resistant making it extremely durable to conventional damage. It was an upgraded response when it first battled Wolverine and Sabretooth after its failure to terminate them. (Wolverine vol, 2. #50 & 51) Event Trigger
The Shiva robot also possesses an electronic pulse that activates neuro-synthetic implants in the cerebral cortex, triggering a cataclysmic memory backlash that forces the Weapon X member to relive all their excruciating life moments of searing pain, bullet wounds, laser blast and sword cuts, suppressed trauma, heart break, loneliness and shame in vivid clarity all at once. Self Repair
The Shiva robot is capable of self-repair although not as efficient as Wolverine or Sabretooth. It has allowed it to reattach its own head and continue to function, it has system back-ups for its system back-ups for optimum survivability and is capable of generating individual modules from damaged components. Duplication
Whenever each robot is destroyed and inoperable it simply generates a new robotic body at the Weapon X compound for the program to inhabit. There is a limitation to how many bodies it can create but the number is not known, so far it has replicated itself at least 4 times. Stealth
Shiva possesses sound dampeners in order to help it sneak up on its target who possesses superhuman hearing. (Wolverine, Vol. 2 issue # 50). Flight
Shiva is capable of sustained flight and generates gliding wings from the side of his body and arms. ( Wolverine, Vol. 2 issue # 64).
