So that's the opening to Combiner Wars!
The Combiner Wars have begun here in my fan fiction, and as such it's time to list the opening scenario and also the cast of character in this arc!
Kyle Herbert as Ironhide
Kent Williams as Nova Prime
Constance Zimmer as Strongarm, Filch
Peter Cullen as Prima
James Horan or Steven Blum as Wheeljack and Blum doing Starscream
Spike Spencer as Wheelie and Tailgate, Fixit
Garry Chalk as Optimus
Michael Ironside as Ultra Magnus
David Soblov as Shockwave and Senator Ratbat
Clancy Brown as Onslaught and Grimlock
John Noble as Unicron (with voice enhancer lowering the voice and adding a robotic echo to it).
Frank Welker as Soundwave, and Megatron, Gears
Benedict Cumbercatch as Perceptor, Fracture
Corey Burton as Whirl (in his Schockwave voice).
Dean Norris as Knockdown and Red Alert, Sonic Bomber
Will Friedle as Bumblebee, Groove
Mark Ryan as Lockdown, Thunderhoof.
Greg Berger as Jetfire, Defensor, Hot Spot,
Nolan North as Sky Lynx and Smokescreen.
Scott Mcneil as Ratbat, Thrust, and Waspinator
Sumalee Montano as Windblade
Peter Cullen, Gary Chalk, Frank Welker, Scott Neil, Nolan North, Steven Blum, Daniel Riordian, Neil Kaplan and David Kaye would all voice Nemesis Prime/Pax in a high scream voice in a Prime Sky Lynx like voice (making Nemesis Prime sounding like he has dozens of voices at the same time).
Troy Baker as Steeljaw
Kevin Michael Richardson as Bulkhead/Tankor
John Dimaggio as Swerve, and Crosshairs
Zelda Williams as the Mistress of Flame
Tony Jay as Dai Atlas, Kup
The Rock as Cliffjumper, Ginrai Maxúcon
Neil Kaplan as Star Saber
and Fred Willard joins the cast as Swindle.
Steven Blum now voices Prowl

The rest of the cast will be updated as the series progresses.
Combiner Wars will obviously debut the addition of Combiners in my fan fiction, along with a few Maximals. The events of this arc are going to be real permanent in the rest of the series.
