Full Wormslayer does not exist because not all the parts have dropped. I have 5/7 and could take a pic sans helmet/gloves, or you can wait another 2 or 3 years for the other parts to drop.
I think I got a few of those you are missing though it's complicated to put together since some are in storage on ark, some on caly ) Full Dragon M I have on ark for sure, nemesis i'm currently turning into adj so it's half half now )
Give me a message with those you are having trouble finding and I'll move my collection
