| 6 | Omega Ruby | Zubat remains quietly unmoving in a dark spot during the bright daylight hours. It does so because prolonged exposure to the sun causes its body to become slightly burned. |
| 6 | Alpha Sapphire | Zubat avoids sunlight because exposure causes it to become unhealthy. During the daytime, it stays in caves or under the eaves of old houses, sleeping while hanging upside down. |
| 7 | Sun | It sleeps in caves during the day. It has no eyes, so to check its surroundings while flying, it emits ultrasonic waves. |
| 7 | Moon | When exposed to sunlight, they suffer burns. The frequency of their ultrasonic waves can differ slightly from colony to colony. |
| 7 | Ultra Sun | It has no eyeballs, so it can't see. It checks its surroundings via the ultrasonic waves it emits from its mouth. |
