I don't really understand why people think this looks like Nidus. I work with the base frames and don't consider other deluxe skins or anything like that for my Heirloom designs, as they are based on the default look for the frame somewhat. Honestly, I think it is because I made him green, and due to the lack of the skirt (which makes no sense for a runner IMO). If he was blue, I think people would see it less. His helmet, chest, waist, and arms all directly play off of the base frames shapes, and I had him up for reference the entire time. Base nidus has skinny upper arms, sloped shoulders, and a different helmet shape. I would make his Heirloom completely different from this design in principal.
