Anti-backwards crystal

When the single non-local metaparticle was accidentally created by Professor Hubert J. Farnsworth, another crystal made of pure anti-backwards energy was created.

In an ill attempt to create a more durable harpsichord wax Professor Farnsworth put several dark matter (then useless) pieces in a particle accelerator, but because of quantum physics the dark matter transform into a crystal that links all dark matter and makes it usable as fuel. With one drawback, if it ever came close enough to the anti-backwards crystal, it would render all dark matter useless again. Mom had stolen the Metaparticle, but thought the Anti-Backwards Crystal was destoyed. when the fuel prices went skyrocketing, the Planet Express crew set out to take the anti-backwards crystal close enough to the metaparticle. After an adventure in an alternate reality, the crytals met and all Dark Matter was made useless again.

Trivia

 * When the Professor put the anti-backwards energy crystal close enough to the metaparticle it made a reaction on all dark matter and through Bender's imagination created Cornwood.
 * The crystal is shaped like a twelve-sided die.
 * It is similar to the Die of Power
