Facebook group TFND has posted official photos of Power of the Primes Leader class Nemesis Prime! Probably destined to be an exclusive, Nemesis Prime comes with a sword which transforms into a bird companion named Giza - the name of Transformers Prime Nemesis Prime's Arms Micron! We also get our first look at the "Orion Pax" inner robot, whose name and/or true identity are not currently known... but that's sure not Pax's head. Keep reading!
In addition to Giza, Nemesis Prime comes with a new-mold sword that can only be patterned after the Armada Dark Saber/Vorpal Saber. In a G1 body with Armada and Prime weapons, this Nemesis Prime represents nearly every continuity that an evil copy of Optimus Prime has appeared in... except for the originator of the trope, the 2001 version of Robots In Disguise. If the inner robot is named Scourge, that would cover everything. (We're not counting The Last Knight here, since that "Nemesis Prime" was just a brainwashed Optimus Prime with no visual differences except for purple eyeballs.)
