*dizzy* Sorry... The Mallet of EPICNESS just smacked me right upside the head.
Listen to this:
Okay, so we have Rex, Six, Holiday, Bobo, and White in a new rebel organization right? Well, if/when VK comes back, he's not likely to like BK's methods of using mind control on Evos as that would be a threat to him.
If VK comes back, Breach will definitely come back (because it would be too freaking cruel to leave her out!!!).
Skalamander and Biowulf, as my Batman and Robin theory states, are out there somewhere on their own.
There is also the Jungle Cat Evo to consider. He is either under the control of Providence, on his own,
turning the Biowulf/Skalamander Batman/Robin team into a Biowulf/Skalamander/Cat Batman/Robin/Nightwing team, or with the rebel team.
Noah is likely to come back, because he's REX'S BEST FRIEND. Therefore, he is certainly not being exed out here. And he probably learned some sweet street fighting skills during these past six months (in my mind's canon).
With Noah will probably Annie and Claire. I can see Annie learning a thing or two about guns...
Also, the Hong Kong gang is close to Rex, so they will likely come if they are needed.
Six can use his connections to get the Numbers on his side, because I'm SURE they all owe him something. Otherwise, Five can force them to go along with it. She seems to be the type to do that. ^_^
Abuela and the werewolf Evos are surely gonna make a comeback. They're just too awesome! Besides, they need to support the family. Aka Rex!
Valentina and the Green Fist organization are DEFINITELY not gonna like what BK is doing.
Gatlocke may be broken out of his prison for some reason or another. For some reason, I see him fighting for Black, but his love for anarchy is more likely to sway him toward our rebels.
If Van Kleiss was able to come back from being dissolved, that could mean that Rylander can also come back with some sweet science skills.
I dunno if Beverly is going to ever come back, but if she does, she'll have gotten some training from her big sis.
Sergio is likely to be against Evo control, so he and his sea army may give some support to the cause.
And Callan...he'd better be there somewhere!
Oh, and let's not forget Kenwyn!
Moving on to the oppositionBlack may hire the help of Cain. We all KNOW how much of a beef he has with Rex and Evos in general.
Quarry is also alive, as far as I know! He'll probably try to work for BK in order to secure his own safety.
Caesar built ZAG-RS, so he has control over her/it.
No-Face may be desperate enough to make a deal with BK in exchange for his freedom from the Bug Jar.
Maybe Doctor Moses will make a comeback.
So, what does this mean? It means that, for the season finale, we get to see a great big final battle with... *pulls out list*
Rex, Six, Holiday, Bobo, White Knight, Van Kleiss, Breach, Biowulf, Skalamander, Valentina, Noah, Sqwydd, Tuck, Cricket, Circe, Dos, Trey, IV, Five, Abuela, the werewolf Evo pack, the Jungle Cat Evo, Gatlocke, Callan, Kenwyn, Sergio, Rylander, Beverly, all rebel organization grunts, all Evo Pack members, Sergio's fish army, and all Green Fist grunts
VS.
Black Knight, Caesar, Cain, No-Face, ZAG-RS, Moses, all of the collared Evos in the Petting Zoo, all of the Evos in the Bug Jar, this mysterious committee, a strike force of black chess pieces, and any other surprises BK/Caesar may cook up between now and then.
*kaboom* Whoa...my mind just exploded from sheer epicness...
