Can't a few of these people just teleport out of it or somesuch?? Or phase through it?
And it might hold, say, King Thor. But he'd take one look at WW, send a lightning bolt or Mjolnir or something at her, and once she's knocked down, getting out the lasso would be easy pie. So yes and no for most of these people because of that. (i.e. Big G might get held, but then he'd wipe WW from existence and casually take the lasso off).
Juggernaut: Current Jug’s is toast but Classic I see telling the truth but not holding him. Can’t break it but could drag her were he wanted to go and I can’t see it compelling him to obey.
Thanos & Darkside: I don’t think she would want to know the truth.
Dr. Strange: If he knew it was coming then maybe finds a way around it but normally he is toast.
Phoenix: Don’t think so, it might hold it but not control it and I don’t think the Phoenix needs to lie.
Galactus: If she could get it on him maybe but I doubt it very much. Hell he might just suck up the energy from it.
