Henroth:
Between the Blacks Orcs, Who he’s the leader of the rebellion?
He’s one great Black Orc boss? or… One group of Blacks Orcs boss?
I imagine that to be one young Grimgor, that He and one group of supporters, after of the defeat, to go toward the Realms of Chaos, for later, go back to Old World. :hat off
Ghrask Dragh:
Not sure if they are using the same timeline but in the WD presents CD they say the uprising happened in the year -100 but there is no mention of grimgor until the year 2257, would have been cool though.
I’m not sure how long the orcs live but the ultimate orc, Gorbad Ironclaw, is one of the first Warboss’s mentioned after -100.
To be honest though I think it’s a good idea to create your own character, the black orc warboss that led the rebellion, would be pretty cool 
Kera foehunter:
well maybe he talking now in the present!!!
Ghrask Dragh:
Oh… well then it’s Grimgor, hands down
Henroth:
I'm not sure how long the orcs live but the ultimate orc, Gorbad Ironclaw, is one of the first Warboss's mentioned after -100.Well... it's possible that the magic of Chaos him help.

Maybe Grimgor’s ancestor, from whose spores Grimgor eventually came forth. A true mold of the original Black Orks.
Baggronor:
Well, Grimgor and his boys spent years wandering the Chaos Wastes, where time flows differently, so who knows? :cheers
Ghrask Dragh:
So we are thinking that while grimgor was in the wastes he was sent back by an enemy of Hashut to start the uprising of the black orcs against the Chaos Dwarfs… thats pretty f’n cool and just about as insane as it gets! :hashut

Well, Grimgor and his boys spent years wandering the Chaos Wastes, where time flows differently, so who knows? :cheersi second that notion!

Grimgor didn’t seem too bothered by allying with CDs for Storm of Chaos.
Swissdictator:
I suspect the leader was likely killed in the mayhem. I’ll name him Langdon for purposes of discussion.
I like the idea that Langdon was an ancestor of sorts for Grimgor, I could get into that concept. Though I could get into the concept it was Grimgor then he wondered the Wastes messing up time (as I doubt Grimgor would know what to do with a DeLorean).
I think those are the two most plausible scenarios, Langdon or Grimgor the Realms wonderer. Langdon makes a little more sense, Grimgor makes it more fun and fluffy. For scenarios, theme events, I’d probably go with Grimgor, if I didn’t… I’d just use Grimgor’s rules.
AGPO:
We’ll never know, make him up thats part of the fun!
BilboBaggins:
I think I’d go with Langdon using Grimgor’s stats.
Reasoning
1. I like the idea of an ancestor of Grimgor leading the rebellion.
2. It would give Grimgor an ancestorial grudge (hardwired into his fungus DNA) against the smaller greenskins. That will be another brick in the wall that leads him to banish all goblins in the 'Ard Boyz army.
3. I can’t see Grimgor getting his hands on a DeLoren or a TARDIS to go back, or forward, in time. Forget the fact he probably wouldn’t fit in a DeLoren let alone be able to drive it.

I'll name him Langdon for purposes of discussion.It is just me or does that sound like an elf name?

I’m sticking with Langdon. 
Landgon from Public Relations. LOL
Thane Godri GoblinSlayer:
I’m sticking with Balgar the BoneCrusher, a massive black orc who died after three bolt throwers fired at him simultaneously and the sneaky git chieftan stabbed him in the back. :hashut
Godbob and his jolly rogers:
Although I highly doubt it was Grimgore using his rules would be pretty cool
IMO there was no leader just a lot of p***ed off Orcs that wanted a fight, and got it
Godri, I like you’re idea of a SG stabbing him in the back
Onii One Orc:
When are orcs ever not p***ed off and looking for a fight?
I don’t know if Grimgor started the black orc rebellion, or just managed to claw his way out of the Chaos Wastes through sheer stubbornness, but his fluff is some of the coolest out there.
dedwrekka:
Grimgor didn't seem too bothered by allying with CDs for Storm of Chaos.Zug? When did that one happen?
