Boys II Planet () is a South Korean reality competition survival show created by Mnet. The show followed the process of creating a new global boy group. It premiered on Mnet on July 17 and 18, 2025, at 21:00 (KST), initially divided into two programs, but merged in episode 3. The show ended on September 25, 2025, with the formation of an eight-member boy group named Alpha Drive One.

The show serves as the sequel to Girls Planet 999 and Boys Planet. It has a spin-off show called Planet C: Home Race, featuring the previously eliminated Planet C trainees, which premiered on Mnet Plus on December 6, 2025. The show debuted a seven-member boy group known as Modyssey (stylized in all caps).

Background and production On July 29, 2024, a CJ ENM official announced that they would launch Planet B, a new Mnet program that would for the first time demonstrate the recruitment process for K-pop survival programs. In addition, men of all nationalities who were born before January 1, 2012, were eligible to apply on August 10.

On November 26, 2024, CJ ENM confirmed the launch of the second season of Boys Planet, which would be called Boys II Planet, where two groups debut simultaneously. It was slated for release in 2025 and would be broadcast simultaneously in South Korea and China.

The first round of recruitment ran from November 22, 2024, to January 26, 2025, which received applications from 105 countries. The second round of recruitment started on February 3, 2025, until March 2, across eight cities in Asia for the C version and until March 23, for the K version.

On May 13, 2025, Mnet confirmed the premiere dates of Boys II Planet to be on July 17 for the K version, and July 18 for the C version. Following the same style and premise, it comprised two distinct audition programs that were concurrently created and aired in two different languages. It was also the first-ever international K-pop twin project, as both groups would make their debuts simultaneously. On May 23, Mnet announced the changes of the show's format, from having a twin debut system to a single, unified debut group. Furthermore, by working with international partners, including those in Greater China, Mnet disclosed that they were actively looking into ways for the contestants to pursue musical endeavors outside of the show.

On June 5, 2025, Mnet announced the master lineup for the show, namely Lee Seok-hoon, Kinky, and Kany for Boys II Planet K, while Kim Jae-joong, Xiaoting, and Jrick for Boys II Planet C. To ensure that training and evaluations were fair and unbiased, Lim Han-byul, Hyolyn, Baek Koo-young, and Justhis would serve as masters for both K and C groups. In addition, Zerobaseone members' Sung Han-bin and Zhang Hao would provide advice and support to the contestants as the special idol masters.

The program would be broadcast live in South Korea via Mnet and concurrently in Japan via Mnet Japan and the streaming service Abema. Viewers in Canada, USA, Russia, Singapore, Thailand, and Vietnam would be able to access it globally through the digital portal Mnet Plus. It would also be available on the official YouTube account for the show and on TVING. More international distribution was planned, and soon after the Korean broadcast, the series was anticipated to be streamed on sites like Viu, Viki, and iQIYI. These channels would cater to audiences in the Middle East, Africa, Australia, New Zealand, Taiwan, and Southeast Asia, including countries like Singapore, Malaysia, Indonesia, Thailand, and the Philippines.
