Lockon occupies a niche between Cripple and Stun. If it hits, the target cannot dodge, but they may still attack or perform other actions on their turn(ICly they may be limited in how far they may move, however). Lockon attacks can be special 'target-painting lasers' that don't actually freeze the target but guarantees an additional hit, or can be glue-guns or ice beams or gravity rays that actually pin someone in place(or drastically slow them down), letting them still fight back but unable to avoid an incoming weapon.
