Another thing that made me think Killy felt Marvel Legend-ish, was how sturdy he was in-hand. Just as
>>6739048 said, Killy is delightful to pose; nothing about him feels delicate whatsoever, I feel like I could comfortably let a child play with him.
Poseability is excellent too. All the joints you'd expect are there (including hidden swivel joints above his shin guards, an articulation point I'm used to seeing mostly in Marvel Legends, heh) and the range of motion is great. The one exception would his torso; though there is articulation in the torso (including a ratcheting ab-crunch), it is hindered a bit by the PVC jacket placed over it.
My favorite thing is how they hid the shoulder joint with the armor pads, looks fantastic.
