Transformation Lock Lens

- The transformation lock lens is a weapon from the Beast Wars portion of the Generation 1 continuity family.
The transformation lock lens is a Predacon weapon invented by Tarantulas. The device levitates in the air and shoots a pink beam through a round lens that traps victims in their beast modes, rendering them relatively defenseless.
The lens appears to have either rudimentary artificial intelligence or sophisticated programming that helps it distinguish between friend or foe, dodge enemy fire, and hide itself for later dramatic entrances.
Repairing the "lock" is done by a spending some time in the Predacon repair chamber, and presumably the Maximal CR chamber.
Fiction
Beast Wars cartoon

Tigatron was assigned guard duty as the Maximals built a signal array to contact a probe from Cybertron. Tarantulas attacked him using the Transformation lock lens, which trapped Tigatron in his beast mode. When Cheetor came to help his fellow cat he also succumbed to the device while Tarantulas cackled on the sidelines. The pair were taken prisoner and brought back to the Predacon base.

Later, the Predacons attacked the Maximal signal array and Dinobot, Rattrap, Optimus Primal and Rhinox were all zapped by the lens and lost their chance to contact the Cybertronian probe. As Megatron prepared to destroy them, Cheetor and Tigatron appeared on the scene, having escaped from the Darksyde and fixed themselves using its repair chamber there. The catbots' firepower destroyed the transformation lock lens. The Probe
