Judging from what can be found in this book, there are not many true facts known about Pumyra. The best we really have is speculation and guesswork.  But the Thundercats have never been stopped by minor details like that.  Bengali, Tygra, and Panthro forged ahead on this book as though they were omniscient and could confidently relate every particular detail concerning Pumyra.  To clear things up, they can't.  But they made a good effort.  And so without further rambling from me, I give you The Unknown Puma.
