A Phonic disruptor has the ability to stun opponents, among other powers.
History
Mrs Wormwood had one in the form of a ring which she used to combat her fellow Bane and put Gita Chandra in a trance. It only stunned the Bane. She complained that after Mr Smith put her in a containment vortex that this drained the ring's power. When working at full capacity the ring could create a discharge so powerful it could literally blow an adult Bane to pieces. Mrs Wormwood appeared to be able to use the device to target certain people as she managed to attack her fellow Bane without harming any humans in the vicinity or herself for that matter. The ring was lost in the portal to Horaths dimension and its discharge allowed the opening to close sealing Mrs Wormwood and Kaagh in that universe forever. (SJA: Enemy of the Bane)
