Challengers must battle through ten areas, each containing ten Trainers (Zones), to pass the challenge—a total of one hundred battles.

In Colosseum, it is first visited when it becomes under attack by Cipher, led by Cipher Admin Dakim, who possesses a Shadow Entei. Colo 5

The mountain itself is exceedingly large and has a variety of terrain, ranging from basic rocky crags, to the volcanic inside of the mountain, to the lofty peaks. The pathway up Mt. Battle is made with metallic platforms suspended in mid-air with propellers. Colo Bonus 5 XD Bonus 4
