Transwarp wavefront

The transwarp wave was one of the results of the destruction of the Vok Planet Buster at the end of the first season of the Beast Wars cartoon. The wave traveled outward from pre-historic Earth, through space and time, and eventually reached Cybertron.

The Tripredacus Council was able to intercept and disrupt the wave before it reached Cybertron proper, and sent an agent to take care of the problem that it represented.
