Okay, let me go over this and make sure I've got the idea.
Eleki and Drago are stored away in Gigas's main workshop which is hidden away in the Crown Tundra.
Eleki is hooked up to all the tech Gigas made as a power source and she needs to be powered down before the MC can breed her, maybe she was left on full power to keep everything running and goes into MAXIMUM OVERDRIVE when everything is unplugged from her body.
Drago was meant to be part of a much bigger creation that was never finished, Gigas doesn't have the materials to finish the project but rebuilds Drago's head into a full body, Gigas then falls asleep as Drago activates, the battle lasts until Drago accidentally wakes Gigas up again, Gigas grabs Drago and changes her orders from ALARM CLOCK to LOVE MASTER.
I think I can make that happen
