Well, I will gladly help brainstorm ideas for what they can do if you have anything they could possibly [and legitimatly] do, I already know they are space worthy [only needing internals] and immune to radiation, but really at risk from EMP's due to their mechanical nature and they can't heal bythemselves, Maybe they could get a ability in the ability tab were they can repair minor internal damage [below 100] with a long rechage time [like it needs to be at 100 to use and has to recharge] maybe this ability could fix some minor external damage and stop bleeding temporarily?
