Transwarp cell

Transwarp cells are technology from the Beast Wars portion of the Generation 1 continuity family.

A transwarp cell is an essential component of a Transwarp Drive, providing whatever motive force it is that can propel a starship through transwarp. They are sophisticated enough to be programmed to follow specific courses and even affect the systems of the spacecraft they're installed into.
