The Sword of Kings, Poo's ultimate weapon, increases his attack by 30. Any other weapon he equips that all party members can use actually lower his offense. To obtain the Sword of Kings, you must fight the Starman Super in the Stonehenge base BEFORE beating Starman Deluxe. Defeating Starman Deluxe eliminates the Starman Super from the game which means you have no chance of obtaining this weapon. You have a 1/128 chance of obtaining the Sword of Kings. If you can't stand the suspense of fighting each and every one, have Jeff use his spy ability on each Starman Super to try and locate the sword.
