Boss
The player approaches an ancient ruin, but shortly afterwards, Regirock appears and attacks the player, believing them to be an intruder. After defeat, Regirock stops to search for a pattern in the player's memory, and it finds a match. It turns out that the three intruders (later revealed to be a Swellow, Electrode, and Lampent) were "terminated". Afterwards, Regirock returns to its base.

 * Rock Diamond

Gemstone Grotto
Once the dungeon is completed, the three miners find out that the player defeated Regirock and thank the player.


 * Flicker: Fellas, look! I knew I heard strange noises comin' from the ruins!
 * Bombastus: Y-you fought that monster? And defeated it?! I can't believe it!!
 * Madge: You've saved us! Thank you so much!~
 * Flicker: We're the minin' team that was sent down here by Foreman Jerico. We were surprised enough to find diamonds, but we weren't expectin' to find these ruins.
 * Madge: We kept excavating... Made our way into this room, and then we tried to leave, we were confronted by that monster!
 * Bombastus: It attacked us... We aren't fighters, so we were no match for it... We managed to hide out in here without it coming back after us.
 * Flicker: Doesn't matter now, we're free! Thank you kindly, explorer. We found some treasure while we were clearin' out this room. We'd like you to have some of it!
 * Flicker: There is an exit just to the north end of this cavern, we left your reward there too. We should be going now... Foremon Jerico has probably been waitin' for us. Farewell, Explorer!
