Would the tokens made by TG1 be able to use the stats and powers of TG2? If stats conflicted, I assume the controlling player chooses which to use?

Would all TGs be able to use Willpower after one of the tokens is KO'd, regardless of who produced it?

1) yes
2) yes

surprised they didn't make this one a unique (doesn't break the game, but would have been thematically appropriate)

Not sure. But I think it's a no due to the use of "They replace their..." and "When one of them is KO'd...". I read that as refering back to the bystander tokens placed by this specific triplicate girl rather than any triplicate girl bystander token on the map.

But I can see it working the other way too. So...

Past rulings tend to support this assessment.

I am waiting to see the "Things to add to triplicate girl to break the game" threads.....

^^Infinity Gauntlet^^

the only problem with that is, well, which one's with which tokens

it'll get confusing quick

Well, it's also thematically appropriate to have an infinite number of Luornu Durgos as the modern version of her has learned to replicate herself without limit. And the threeboot version was similar, coming from a planet where all the occupants were her.

The tokens can only be used with the Triplicate Girl that placed them. Whenever a power says the figure's name on it it basically means "This figure" it would say "Any friendly character named _____" if it meant anything but "this specific figure".

Here's an example:
Does that give every Superman on the map Invulnerability? No. Just the one that has that trait. It's the same thing with Triplicate girl.

Although, the way it is worded, when She's KO'd she can KO another Triplicate girl's token and heal.

"Fighting as One" works with everyone named Triplicate Girl. Even the ones from Origin.

No more confusing than trying to remember which Multiple Man/Mysterio is which.

but that's the actual point of those figures. they're designed to be indistinguishable. they're built with the confusion as an element of play

by your interpretation of the power you'd want to know the specific figure and which tokens go with it. it's doable, but oof, no fun in that

I played a game with henchmen using multiple bosses. 3 goons per boss. I used coloured stickers(ripped bits of post-its actually) to remember which goon belonged to which boss. It's not that hard to do. Just label them in some way, problem solved.

exactly. "it's doable, but oof, no fun in that"

Someone has the picture Triplicate girl bystander?

Depends on what quality you want. If you just wan't to see what it looks like it can be seen in this video at 13.28.
