If I use Radiant Alakazam's "Painful Spoons" Ability to move two damage counters from one of my opponent's Pokemon to a Fusion Strike Pokemon with Fusion Strike Energy attached to it, what happens to the damage counters?
Since the opponent's Fusion Strike Energy prevents all effects of Abilities done by your Pokemon, if you choose to move the damage counters to a Fusion Strike Pokemon with Fusion Strike Energy attached the damage counters would be discarded rather than moved onto that Pokemon. However, if you choose a Fusion Strike Pokemon with Fusion Strike Energy attached as the source of where the damage counters would be moved from, they simply are not moved and the Painful Spoons ability stops there.

If I have a Klawf ex with "Counterattacking Pincer" Ability and Rugged Helmet attached to it, what happens if it gets damaged by an opponent's attack from a Fusion Strike Pokemon that has a Fusion Strike Energy and a Double Turbo Energy attached to it?
The Counterattacking Pincer ability and Rugged Helmet are triggered simultaneously, so you may choose the order in which they are applied. If you choose the Counterattacking Pincer ability first it will fizzle due to Fusion Strike Energy. However, if you choose to use Rugged Helmet first you can put the Fusion Strike Energy into the opponent's hand and then you can use Counterattacking Pincer to discard the Double Turbo Energy.

If my opponent has Spiritomb with the "Fettered in Misfortune" Ability in play, does attaching a Fusion Strike Energy to my Genesect V allow it to use its "Fusion Strike System" Ability or not?
Fusion Strike Energy protects Genesect V from the effect of Fettered in Misfortune, so yes it would be able to use its Fusion Strike System Ability.

If I use Sky Seal Stone's "Star Order" Ability and then my Basic Pokemon V's attack knocks out my opponent's Active Mew VMAX with a Fusion Strike Energy attached, do I take an additional prize card or not?
Fusion Strike Energy prevents all effects of your Pokemon's Abilities done to the opponent's Fusion Strike Pokemon the energy card is attached to; but the effect of Star Order is not on the opponent’s Pokemon, so you get to take the extra prize.

Does a poisoned Fusion Strike Pokemon with Fusion Strike Energy attached take additional damage counters from Radiant Hisuian Sneasler's "Poison Peak" Ability?
No, because Poison Peak is an Ability and Fusion Strike Energy prevents all effects of your opponent's Pokemon's Abilities.

If Temple of Sinnoh is in play, does Meloetta's "Melodious Echo" attack still do 70 damage for each Fusion Strike Energy attached?
Yes. Temple of Sinnoh removes all effects and provides 1 Colorless energy, but it does not change the card name to be something other than "Fusion Strike Energy". So Melodious Echo still does 70 damage for each attached Fusion Strike Energy you have in play.

If I have a confused or poisoned Genesect V with 2 Fusion Strike Energy attached, and my opponent has a Cradily with the "Swaying Strangle" Ability in play, would I be able to Retreat after I have discarded the 2 Fusion Strike Energy cards as the cost, or would I no longer be able to Retreat?
Since you began the Retreat process while Swaying Strangle was prevented by the Fusion Strike Energy, you get to complete the action and Retreat even after discarding the 2 Fusion Strike Energy cards. The behavior is also similar with Flygon's "Labyrinth of Sand" ability or Snorlax's "Block" ability.

If Dusknoir with the "Spectral Breach" Ability is already in play and then Fusion Strike Energy is attached to a Pokemon (either mine or my opponent's), does Fusion Strike Energy prevent "Spectral Breach" from affecting it, or does "Spectral Breach" disable Fusion Strike Energy's effects?
When Fusion Strike Energy gets attached to a Pokemon it prevents the effect of Spectral Breach, therefore providing every type of Energy and preventing all effects of your opponent's Abilities done to that Pokemon.

If my opponent has Goodra with the "Slimy Room" Ability in the Active Spot, do I still have to flip a coin to attach an Energy to one of my Pokemon that already has a Fusion Strike Energy card attached to it?
Yes you still have to flip a coin, because the Slimy Room Ability is acting on you the player not on a specific Pokemon; and Fusion Strike Energy's effect applies to the Pokemon it is attached to, therefore it does not block Slimy Room's effect.
