Is the Hearld of G affected by his PW my thought is he shouldn't as he is aprt of Gs build

He is still a seperate piece for all game effects. Pulse wave would hit the herald if in range.

If you are talking about any of the powers that Galactus gives to that character? If Galactus is not in range of the Pulse Wave, he would still get the +1 Bonus, but all other Powers/Abilities are possessed and Used by that character and would be ignored.

Ok cool thnx so tech Hearld could b hit and just lose the +1 that G gave him but we r using feats at this venue and using that PW feat that allows u to use printed Dam instead of 1 my thinking was if thanos pulled G and Hearld over I'd use that feat , may have to think of another plan

if a character is being pulse wave, other game effects does not effect it, this would be the same if someone outside of the pulsewave area perplexed the character, he would would not get the bous so how would galactus be different

If a modifier is coming from a character outside the pulsewave range, such as a character with perplex, then their powers are not ignored and the character would continue to have the modifier.

Since the powers/abilities granted by Little G are actually used/possessed by the herald, then they would be ignored. The Modifier granted is not used or possessed by the herald it is just an effect of Little G's trait and no-one else.
