In raid events, the hidden boss is triggered after you have:

1. Reached the 50 mark milestone (50 degrees)

2. Discovered and defeated the 30 versions of the normal boss. In this case, Gynoid Level 1-15, and Gynoid EX Level 1-15.

3. Defeat the first hidden boss (900,000 hps).

The final hidden boss should appear. Usually 10,000,000 hps, with an automatic x2 damage.

The random bosses, like Icene, Icy Pillar Prince, give little to nothing. You might come out with a baby dragon sometimes, but it's mainly to boost your repel count to reach the 60 repel reward.
