this is the robot hijacker mark 2.5 (I'll upload pictures of the failed mark 2 experiment later).
Smaller than it's predecessor, this was achieved using an AI compression technology, allowing the entire robot's processor to occupy the same space as the head of the previous model.
Unlike the Mark 1, the Mark 2 is mobile, using four clawed limbs. It's primary weapon is the forward "mandibles" which are in fact twin vibro-blades, which can piece energy fields and AEGAKS armour with ease.
and just to show it's versatility here is it taking a few more of my designs.
I've kept the underside completely free of any detail, this means that it is pretty much universal. So long as it can find even 2 studs, it can sit against any frame. The limbs and head can be angled so that it can see once combined and doesn't clash into the limbs or frame of the host AEGAKS.
I downloaded the ARKHAM frame to show that it would fit just about any design, not just my own.
I quite like how the four red claws/manibles look a little like eyes, sort of like some demonic spider's face.
Apart from the eyes and claws I kept the colours dark deliberately. A. most Robot tech seems to be black as the primary colour. B. This thing isn't capable of tackling a full sized, fully armed mech single handed, so it's primary weapon and tactic is stealth. If they can't see it in the dark, then it can sneak up on the cockpit, cut through the linkage ports and lift the cockpit module off, then attach itself to the corpse like a hermit crab taking a discarded shell.
due to it's smaller size I'd speculate that there isn't a great deal of intelligence here, so perhaps it operates by remote feed from Drone one.
I mentioned a Mark 2 failure. This was a slightly different design featuring a chainsaw as it's main weapon. While I liked the look it didn't feel right somehow. There was also a slightly bulkier version of this model, but it proved difficult to attach to some designs or left a large gap, so I simplified it.
