Mission > Creation Mission

Mission ini ditayangkan pada episode 9-10, namun pengungkapan lagu untuk misi ini sudah ada pada akhir episode 6 sebelumnya. Penonton/Planet Guardian diminta untuk memilih siapa yang akan menampilkan satu dari lagu yang telah diungkap melalui aplikasi Universe.
54 peserta pada Combination Mission terbagi menjadi empat kelompok berbeda untuk empat lagu Creation Mission, setiap lagu Creation Mission terdiri dari 2 tim sebelum babak eliminasi berikutnya yang terjadi di tengah-tengah masa latihan. Pada mission ini, salah satu peserta dari C-Grup yakni Xu Ziyin mengundurkan diri dari acara karena masalah kesehatan. Eliminasi berikutnya menyisakan 26 peserta, sehingga mereka harus menata ulang dan mengubah formasi lagu, baik itu mendapat tambahan anggota karena kekurangan anggota tim maupun mengeluarkan anggota karena kelebihan anggota tim.
Dalam mission ini, tim pemenang akan mendapat benefit berupa penggandaan suara voting selama 24 jam terakhir pemungutan suara. Selain itu terungkap pula bahwa akan ada mission lain yaitu O.O.O Mission di mana peserta akan menampilkan lagu tema pada acara ini yaitu "O.O.O (Over&Over&Over)" versi debut, anggota tim juga dipilih oleh Planet Guardian melalui aplikasi Universe.
