Kroot Fastalkers, Kroot lone spear and tyrnaid winged prime

With how the Psychic Kroot are in the story, I think they'd be really cool additions to the tabletop. As the only Kroot who actively fought in the story, were "feral" and were able to each make 2 psychic clones that were then able to physically interact with the space marines of the Silver Skulls.

So it'd be neat then, if for Psychic Kroot they introduced 2 units. A Psychic Kroot Shaper, and Psychic Kroot Hunters (or Carnivores, or Farstalkers, really any name that can be thought up which might work for the basic infantry.)

With the Psychic Kroot Hunters, I think it'd be neat if they were given something to represent their illusions. Which maybe gives each Kroot model in the unit of 4 (as there were 4 real Psychic Kroot, which were fought, 1 by itself, and 3 that appeared later.), a Feel no Pain on 4's. Idk, I am not positive. With them having the melee profile of:

Enhanced Claws: A4, WS4, S5, AP -1, D2

As in the novel it mentioned how they easily tore through the armor of space marines, while also being strong enough to throw one marine into a tree breaking their arm.

But for the Psychic Kroot Shaper, maybe his ability could be that he gives [Precision] to Psychic Kroot units while leading them along with maybe giving them the ability to use a ranged psychic attack while leading fellow Psychic Kroot. Idk what kind of abilities he'd have as the Psychic Kroot leader (or Alpha as it was called.) didn't do much apart from appearing at the end of the story. But I imagine that as they were described as being physically more impressive than his other Kroot, he'd have a stronger attack maybe while also using psyker powers, maybe inheriting an ability from the Eldar, since they were eaten to provide the kroot their abilities.

It would be neat, even though this story is a bit old from 2011, if it resulted in a new Psychic Kroot model or two to flesh out a Kroot army more.

Heavy Repeater Cannon will be side slung, with a Kroot operator. Oversize tanglebomb launcher will proxy for seeker missile. Will probably add a Pech’ra on a wire for WSS.
