I think the problem is less of how Specter plans to move and more of what Specter did.
Specter came in and derailed a lot of things. You can't just
do something like that. You have to ask. I was a little iffy to him at first, but no one else seem to mind so I said "Whatever" and let it go. Of course, now Specter's presence is actually derailing things actively, while these things are going on-
A) Z's plan executes, Yang is going berserk, Snake prepares to foil it
B) Team Hiro confronts the Doomslayer, and are joined by Cut and Elec Man
C) A huge battle is on the verge of happening
D) Black Lion plans on taking down the villains
E) The final charge upon the Labyzinth
And now Specter is thrown on that, possessing folks and doing a bunch of random things, and apparently can hop through dimensions at will. This is going to mess up quite a bit. If it was just his apes being deployed on the ground, I'd think it'd work a little better, since, y'know, it's a third army atop the others
(And Snake can probably deal with them, he's done it before) but now he's just hijacking the plot.
I get
why you want him, you want a big card carrying villain. A big boss to control. I get that because Eevee has one, Lettuce has one, I'm planning one (Big bad general of darkness duder). But the difference is that we don't just drop them without asking. And honestly it seems Specter could cause some honest damage to the long running RP. An RP isn't entirely premeditated- just like DnD, the GM or DM has an outline of some sort that he can bend from to get an end goal. But we generally need
some idea of what's going to happen, especially if you just drop it on us like this.
To close things off, I think Specter can work, but he needs his own place in the RP and now is certainly not the time. I'm not sure what's happening in Camelot, but I already had a bit of something for the RP to follow once the groups land in Goldenwalk City (Aka HeroSquad) or in the general vicinity. Specter showing up in a place like HeroSquad naturally derails things, because in all honesty I wasn't planning out any huge battles. There's not a card carrying villain there. It's much more personal- trying to find some important people who disappeared while also trying to make sure the city doesn't go up in flames, since, y'know, a dozen or so people from alternate dimensions are showing up.
I don't particularly think this against you Shen. Just like I told Eevee, your a good RPer and a good writer. And I can appreciate that. It just doesn't seem like you thought this situation out very well. I'm not sure what should be done with Specter- he certainly doesn't need to be pulled from the RP, but perhaps you could ratify your latest post to not have him taking over immediately. After all, I doubt the drones could stand up to a few plasma blasts from the Soviets. Encourages Specter to attack from the ground.
One final thing, I know HeroSquad is something that isn't immediately familiar considering I've released zero
anything on them. Honestly I didn't even ask, just mentioned something from it, and Eevee just said it was a good idea and I went with it. I'll plop down a big lore dump so everyone can be caught up- especially concerning the location and time.
