This is Gadget and Lucy (I'll do a full character description when I upload a newer version of them individually)
Brief description: Gadget is a child genius from the future, who has a talent for inventing technology based things. Gadget built Lucy (Lupus Mechanis) as a defence system for The Refuge. After several upgrades that resulted in her having a personality, Gadget fell in love with her. They currently both live happily in The Refuge.
