Hi guys, so this is Gadget and Lucy. Gadget built Lucy as the defence system for The Refuge, she can transform into a giant robot wolf and is basically the ultimate defence. The more he worked on her, giving her a personality so that she could interact with the people and building her an indestructible body, he unintentionally made himself his perfect mate. The more they spoke, the closer they got and soon they became soulmates. Gadget then developed Lucy's appearance to become more feminine. They're living happily together.
