George Takei asks 'Star Trek,' 'Star Wars' fans to unite against the real evil - 'Twilight'

Leave it to a navigator to set the true course.

First, William "Capt. James T. Kirk" took a couple of shots via video at the "Star Wars" franchise, claiming it was derivative of "Star Trek."

Carrie "Princess Leia" Fisher responded. "Where do they go - Klingon? Sounds like a laundry detergent."

Shatner posted another video ... well, you get the idea.

Getting what we hope is The Last Word is George "Sulu" Takei. In a video posted on his blog site on Sunday, Takei called on fans of both franchises to rally together against the vampire menace - "Twilight."

"What is needed now today, more than ever, is 'star peace,' for there is an ominous, mutual threat to all science fiction. It's called 'Twilight.'"
