"AXEL WALKER, the crazy TRICKSTER, likes toys and gimmicks. And this time he's making mischief using things no one can see. Whether it's oxygen, air pressure, or invisible gas, the TRICKSTER is bubbling over with evil schemes. Only the FLASH can outwit the nefarious knave. But soon, WALKER traps FLASH within a special bubble, a gigantic glass sphere free of friction. Without friction enabling him to move, the FLASH's super-speed doesn't get him anywhere. And the oxygen inside the bubble is quickly running out!"
