Light Bender

A Light Bender is a spherical shaped, piece of Cybertronian tech that quite literally bends light. It can create copies of the user or make them invisible. However, the only down side of this unique piece of tech is that if there is no light 'to bend' then it will not work and reverse the affects of the device.

Season 3
In Guilty as Charged, Nightra stole one from an unknown source and frequently uses it to confuse her opponent and to get away from enemies such as Blastwave. However, Strongarm managed to defeat Nightra when she found that the flaw in the weapon is that it allows light for it to work and quickly blasts light which ultimately led to Nightra to be arrested.

In Breathing Room, Steeljaw's Pack has a Light Bender which Clampdown used to render a cargo container invisible so he could trap Strongarm and Sideswipe in it.

In Freedom Fighters, Cyclonus's team of Decepticons used Light Benders to disguise themselves as Autobots, so that they could be elected as leaders of Cybertron. They evidently also supplied the devices to their security forces, as Light Benders were used to conceal efforts to build a space bridge receiver on Earth. The Bee Team successfully disabled the Light Benders, exposing the council as Decepticons.
