much like the Haydees, they were created with human bodies that they found in their storage facilities. the Haydens and Haydels serve a militaristic roles. the Haydens, using genetically altered bodies, show enhanced strength and endurance over the other models and are even taller than a normal human. but the greatest downside is their aggression and tenancy for intense violence. even towards other Haydens and Haydees.

that's where the Haydel's come in, primarily to heal, calm and otherwise keep their respective Hayden from dying, going rouge or whatever other horrors the Hayden might do to itself or others. being rather small compared to even a Haydee (about 1 foot smaller.) they're often shy and will often run away from danger rather than stay unless a Hayden is near by. they usually run away from robots, mutants, lone Hyadens and even Haydees.

the Haydens are often armed with powerful weapons like shotguns and HMGs. sometimes even their hands work as effective weapons of destruction. as well as getting a nice set of armor to wear as they stomp around looking for things to destroy or Haydels to capture and incorperate into their small group.

Haydels, because their main job is to supply and heal their respective Hayden, are only armed with a dinky pistol for self defense and decent armor that could protect them from small arms fire and melee. but that's about it in terms of defense as they are too weak for hand-to-hand combat. they usually lug around a backpack filled with the ammo their Hayden needs and medical supplies that they use to heal and fix wounds.
