Girls Planet 999
Mission > Planet Demo Stage

Mission ini ditayangkan pada episode 1-2, di mana setiap peserta akan di evaluasi berdasarkan penampilan demo mereka. Peserta tampil berdasarkan grup asal mereka, dan akan di evaluasi untuk menentukan apakah mereka dapat dipertimbangkan untuk menjadi kandidat Planet Top 9. Peringkat/ranking awal mereka diumumkan sebelum mereka melakukan penampilan, dan pemeringkatkan berdasarkan tes evaluasi lagu tema selama dalam camp.
Setelah semua peserta telah dievaluasi, para master akan mendiskusikan dan mengumumkan siapa yang akan menjadi Planet Top 9 untuk yang pertama kalinya dari kandidat Planet Top 9 yang telah terpilih saat tes evaluasi. Peserta yang menjadi Planet Top 9 dapat merombak ulang sel-nya atau mempertahankan sel yang sebelumnya sudah terbentuk.
