Following on from either of the above continuities, Vector Sigma later reappeared in Beast Machines. Since we had last seen the computer, it had been equipped with an external shell program known as the Oracle, which allowed receptive Transformers to commune with the Allspark, the well of all Transformer life that Vector Sigma was connected to (a retroactive explanation for how Vector Sigma could bestow life). When the renegade Maximal-turned-Vehicon Tankor discovered the existence of the Oracle and its Vector Sigma core, he was able to access Vector Sigma and recreate its key as part of a plan to trick this era's Megatron into using it on a massive scale to purge all traces of organic life from the planet. Optimus Primal countered with the force of the Plasma Energy Chamber and the meshing of the two energies apparently canceled each other out. Subsequently, Megatron sought to activate the key at the core of Cybertron, but Primal defeated him, and the two enemies were destroyed together.

Famous quotes containing the words beast and/or machines:
“his head
May not lie on the breast nor his lips on the hair
Of the woman that he loves, until he dies.
O beast of the wilderness, bird of the air,
Must I endure your amorous cries?”
—William Butler Yeats (1865–1939)
“As machines become more and more efficient and perfect, so it will become clear that imperfection is the greatness of man.”
