ANTI-PARTICLES: Outwit. // When Annihilus is attacked, any positive modifiers of the attacker's attack value become negative. When Annihilus attacks a single character, any positive modifiers of the target's defense value become negative.

My question is , does Anti-Particles make the opponents attacks against Annihilus - minus instead of + plus ?
For example if Kid Gladiator is at plus +3 ( 14 AV ) and he attacks Annihilus , does it become - 3 ( 8 AV ) ?

Yes, all the modifiers to attack are the inverse of what they would normally be

And then his defense is going to stink when Annihilus attacks him, too. But don't worry, the more Annihilus hits him, the better his defense will become.

Still waiting for an official confirmation on how this Special Power works . . .

There isn't really official confirmation on here. If somebody gets an answer wrong, lots of people will jump in. If only one or two people answer, and it's the same answer - you can probably rely on that.

So yes, if Kid Gladiator is on click one with three confidence tokens and no other modifiers, his attack value when attacking Annihilus is 8. And when Annihilus attacks him, Kid Gladiator will have a defense of 15.

Thank you for responding .
