ASP-021 Manta Dragons:

ASP-021 is known as an x-ray or a manta dragon. The manta dragon is a flying billowy creature shaped like a giant manta ray when viewed from underneath it. This ASP can be up to 70 feet long and can have a 14-40 foot wingspan. Manta dragons are grey, black, or somewhere in between in coloration. It has a tail-like appendage that disappears or fades out behind it, existing in another area or dimension. The creature's neck can extend or push out to a degree. This creature has variable wing shapes and the creature as a whole, including its face, are quite mailable. This is used to adjust during flight instead of flapping its wings, as would be expected under the Reynolds coefficient. It can fold into the dimensional rift on its tail and suck in something from the other side in its place while doing so because of a pressure differential, including living creatures.
