Alliance is battling Galactus and during the alliance recruit my friend (playing Birds) tries to substitute Catwoman for Oracle. The player playing Galactus plays this bores me in response. Can This Bores Me negate substitute?

Also we have a guy trying out Grodd Legend and he raised an interesting question. Monkey See Monkey Do says Play only during your attack step. To play, exhaust a Gorilla Grodd you control. Target opponent chooses a character he controls. Move it to your front row, and it gains the Secret Society affiliation this turn. At the start of the recovery phase this turn, move it to that opponent's front row.
If the Society player ko's the stolen character to Grodd awful's effect would the character still be returned to the opponent's front row at recovery? His question comes from the last line being it's own sentence at the end.

If this bors me negates character payment powers then yes but I don't have it in front of me so text of card would help.

and if you KO the character it goes to its owners KO pile not your, or his front row.

For Monkey See Monkey Do the character is not returned if it is KOed this is due to the fact that the character changes zones when it is sent to the KOed pile so it is no longer considered the same character. When the effect of returning the opponents character to them goes to resolve the original character no longer exists so there is nothing to be returned.

On a related note as Kariggi mentioned when you KO a character that you have stolen from your opponent it is sent to their KOed pile not yours.

Direct from DocX:

For the sake of Kariggi, that is.

1. This Bores Me can negate Substitute, sure...but Galactus shouldn't bother. If the Substitute effect gets removed from the chain, the Substitute card itself goes back to hand, and Galactus doesn't really benefit. (Applies to both Substitute and Terraform, actually.)

2. When a card changes zones, it becomes an entirely new card for game purposes. The character card sitting in his KO'd pile is not the same card that was chosen earlier, and so it's not the card that Monkey See, Monkey Do tries to find. It stays put.

That will help me too DoomStat, thanks.

Well given this wording I believe that he can negate substitution (or at least one try at it) as it is in fact a payment power that reads "reveal this card -> ..." but the substituting person can just reveal the same card a second time so it would just be wasted negation.

in response to the grodd question...i think that if the character is no longer in play it cant be returned to play even to that line of the plot twist.
