Automatons are very durable, with high tolerances for all temperatures. They can survive falls from higher distances than humans, as well as survive deeper deaths in the water, but if they do not completely dry off after being exposed to water, they are prone to rust.
Automatons are, on average, much stronger than humans, but in general are have less dexterity for small delicate tasks
Some can store and release electricity, and can use this power to temporarily stun others or even power-up electronics. However, the more electricity they store, the more stress it will induce on their generator, which could lead to malfunctions or even a complete shut-down. If this happens they need to be repaired by a child of Hephaestus.
Some can also fly, they can reach speeds up to 120 mph, though sustaining a speed over 60mph can cause their systems to overload and require a child of Hephaestus kid to fix them
Automatons are generally faster than most humans, but not always as agile, depending on how they are built, as well as not being overly stealthy
Some can conceal weapons within themselves, and are usually very adept at using a variety of weapons, and what they may not know, they can be trained and/or programmed to know
Some are able to temporarily attract metals to them like a magnet, but the more force they use, the less control they have over what comes back
Some are able to be programmed with knowledge on various things, ranging from combat skills to general knowledge to emotions and feelings. Because they have to be programmed to be able to have emotions or feelings, they are more immune to having them as well. Even if they know what "fear" feels like, they have more control over it so that it doesn't consume them.
Some are able to mimic any sound they hear, from voices to music
Some can record anything being played around them, whether it's music or a conversation
Some have a USB port and can connect with other electronics
They have a higher stamina than most humans, enabling them to push themselves further, as they do not feel "tired", but they still use energy, and that can be depleted if they over extend themselves
They are immune to poisons, as they do not need food and drink to sustain themselves, but they are susceptible to things like acid.
They do not need sleep, but they do need to re-charge their power supply at times
Some can repair/induce glitches in technology. This sometimes allows them to heal minor internal problems in automatons.
They can enhance another machine's speed and/or capacity, but it drains them
They are adept at hacking computers
They can jack in and communicate with a variety of different machines and technology
They can activate and deactivate electronic devices at will
Some can have special equipment that can determine heat temperatures and weak pressure points, store enemy images and data and enhance his accuracy.
