Great Cthulhu then Sidekick: Android (Star Munchkin)

[EpicMage]

This happened tonight and caused a halt in the game:

Players Purple and Blue were in a fight against a monster. Player Red wandered in Great Cthulhu, which causes Sidekicks to flee. Player Blue then said that he would self-destruct his Sidekick: Android for a +12 bonus.

Player Green said that Sidekick: Android couldn't provide the +12 bonus since it had already fled before the Great Cthulhu. Player Blue replied that the Sidekick: Android self-destructed as he fled, which would still provide the bonus. Player Green then said that if the sidekick had already fled, it couldn't activate a self-destruct bonus in the combat.

What is the ruling here?

[DoomedDuck]

The Sidekick has to still be there for the ability to trigger. Since it fled, it can't trigger. It doesn't happen "as it flees". It's just gone.

The effect of the The Great Cthulhu is to nullify your Sidekick(s). Once he's part of the combat, you can't use a Sidekick's bonus or special abilities. You can't react to the card's existence because the effect is immediate.
