So I was watching some episodes of Thundercats, and I realized that Panthro is seen with a tail when he's younger, I have a couple theories of what happened to it, such as it getting cut off in battle, or maybe he cut it off himself so it didn't get in the way when he was fighting, and so on, in any case, it got me thinking of what it'd look like if he still had it in his older years.
Panthro belongs to his respective owners
also shout-out to  zeosilvertooth for answering the question I had in my last Panthro pic
