Restraining Techniques (Kanashibari no Jutsu) are techniques that are used in order to incapacitate the opponent for an opening for attack, or give enough time to the user to perform necessary action.
These techniques include: Bandage Throw, Merry-Go-Round Gum, Lick Twister, Hypnosis, Look into my eyes!, Telekinesis, Pressure Point Attack, Evil Containment Wave, Full-Nelson, Psychic Spark, Time Freeze, Guldo Special, Imprisonment Ball, Sealed Light Beam, Energy Web, Psycho Thread, Energy Rings, Sealing Spell, Demon Eye, Galactic Donuts, Charging Ultra Buu Buu Volleyball, Potbelly Attack, Wrap Attack, Para Para Boogie, Electric Slime, and Time Bullet.
A downside to the restraining techniques is that generally most of them are only effective if the user is more powerful than the opponent. Otherwise, it is completely useless. This is demonstrated by General Blue's Look into my Eyes! failure against Mercenary Tao, and Chiaotzu's Psychic Spark failure against Nappa.
