I think Morphun is just the Leader mentioned because he is organizing the Junkz party in the comic. He is only representing the Junkz, he is not the Clan Leader.
Anyway, at least now we know it is Zlatar is the TRUE Uppers commander, not Zatman because Zatman works for Zlatar.
Hmm, is Copper's aunt going to be a new Sentinel card or will she only play a part in the comic?
Only time will tell.
