Reappears. I have nothing 2 offer but a spare few robot headcanons.
When Riga uses his delusion he begins to . . . not quite glitch but due to the overload of electro he tends to get a bit weird. I’ve mentioned before he gets more erratic/emotional, but. Idk if I mentioned yet the effect it has on more physical things- namely what I’m thinking of atm is his voice, which tends to sort of. . . I want to say ‘stutter’ but ‘glitch’ might also be a bit accurate? The typical robotic voice-glitchy-thing.
The artificial skin that covers Gio’s wrist & hand can be quite easily removed compared to Riga’s ( or compared to the ‘skin’ that covers the rest of Gio’s body ). He doesn’t have a fully complete metal. . . outer. . . skeleton? like Riga does, and because he is a far more. . . sensitive specimen, the fine gears in his wrist, hands, and fingers are especially prone to wear and require frequent tuning and maintenance. There are a small variety of tools that Gio keeps in his bag for this purpose.
Both of the automatons-- though this is FAR more pronounced in Riga, being just barely noticeable in Gio if you were to put your head to his chest- have uh . . . what has been affectionately deemed a ‘whirly-purr’. If you sleep beside them, you will also likely hear them wake up before you see them wake up, b/c like computer systems there’s a lil whirr when they wake up. Again-- something that is much, much more pronounced in Riga than it is in Gio.
Neither of them are fully water-proof, as I’ve mentioned, BUT- a brief moment spent in water won’t kill them, nor will anything like rain or mere splashes of water. Generally it would take upwards of maybe 2 minutes or so of considerable water exposure before they start encountering even a glimpse of an issue. Because he doesn’t have a complete metal casing under his skin like Riga does, Gio is more susceptible to water damage. This is something that’s plagued most of Dottore’s older works; though the things he creates nowadays are far more waterproof.
Both of them. . . have slightly glowy eyes.
