"Medical information" - important info about how they work that doesn't constitute a superpower

• Is a robot. Can't consume human food with the possible exception of using food-grade oil to lubricate moving parts, doesn't need water or air, doesn't excrete much besides heat, doesn't bleed, can't contract organic diseases (but can get malware or glitches), can communicate via wireless connectivity. Can't do Maximilien's electric shock thing, but doesn't really need it.
• Powered by electricity and methanol-based fuel cells. Capable of recharging by either plugging into a wall outlet (they're capable of reconfiguring the power cord if it's incompatible) or consuming fuel; enters sleep mode if their main battery is depleted, at which point they'll automatically begin to charge from their fuel cells if they have fuel in the tank or, uh, enter a deathlike torpor if they don't. They're not 100% dead if they're completely out of power since they can be revived by someone else plugging them in or refilling their fuel tank, but they're rendered inert and can't fix it themself. This is why they try to recharge and/or refuel BEFORE reaching this stage.
• Unreasonably heavy for their size due to being full of steel and silicon instead of meat and bone, making them incapable of floating or of climbing anything that's not built to take a lot of weight. — Not true in Come Sail Away, but they still aren't buoyant.
• They ARE, however, waterproofed thoroughly. Corrosion and short-circuiting isn't a concern even if they're totally submerged, unless the water manages to get INSIDE their body. (Which isn't great for humans either but is even worse for robots.)
• Only has one hand, but it's very dextrous. It's on the left side though so they have to put up with equipment designed for righties. They don't use the end of their gun arm to poke at things unless their manipulator arm is incapacitated (they do sometimes brace objects against the side of that arm) and they don't make a lot of gestures with the gun arm to avoid unintentionally pointing it at someone mid-gesture.
• Has a sense of smell. It's pretty much human-standard albeit calibrated to be more sensitive to organic smells and less sensitive to mechanical smells, but I felt like it merited mention since it's a feature robots often don't have.
• Better-than-human cold resistance, but unexceptional heat resistance. They were built to withstand the weather of a temperate climate year-round, but not equatorial heat.
• Middling network security/firewalls/etc; the factory-installed security features were top-notch when they were built in 2046 (apart from the backdoor installed for the use of the omnium, an Authorised Remote User) but Bastion isn't a good enough hacker to improve upon those much and hasn't had a lot of chances to get other trusted people's help installing upgrades.
• Magnets will stick to their steel components, but they don't use magnetic data storage so it won't cause data corruption even if the magnet is very powerful.
