Hyperbolic Time Chamber

Biodata

Properties and Rules

Use in the Story

• Saigo's simulations — Saigo discovers that he can enter the chamber during a simulation despite the simulator's usual four-month duration. He repeatedly uses its accelerated time for combat training, the Spirit Refining Method, spiritual-energy refinement, and attempts to master new forms 81 87 88 92 105.
• Training companions — Saigo trains with Vegeta III and later Salza inside. Paired combat with Vegeta III produces faster battle-power growth than Saigo's solitary training 87 301.
• Mass training — With the Guardian of Earth's permission, Saigo arranges for thousands of Saiyans and Namekians to enter. One group includes 6,634 Saiyans and 716 Namekians; a reported training round results in all participating Saiyans mastering Full Power Super Saiyan, 4,396 reaching Super Saiyan 2, and none reaching Super Saiyan 3 276 283 312.
• Dragon Balls in simulations — Saigo brings the Namekian Dragon Balls inside and finds that their petrification period can expire under the chamber's time flow. Later use reveals additional cooldown limits rather than unrestricted wishes 301 341.

Hazards and Restrictions

• Being stranded inside — Ling remains after the other trainees leave. While Ling is inside beyond the time limit, the door cannot be opened from outside; Mr. Popo says Ling must be removed before the chamber can be used again. Shenron subsequently retrieves Ling 281 283 286 288.
• Barrier breach — In a simulation, Saigo's energy-charged roar breaks through the chamber's dimensional barrier, briefly opening a passage 82.
• Supplies — Saigo arranges food for large groups entering and warns trainees to track their time so they do not become trapped without adequate provisions 276 281.
