Shown and lampshaded in issue 4 of Fall Out Toy Works with Tiffany having a cooldown smoke after an argument with Baron.
In the same issue, Mr Moth gets 3000 channels and apparently makes the most of them, what with comparing Toymaker's Heroic BSOD with George Foreman after his match with Mohammed Ali.
Another lampshading in issue 4, when Tiffany finds one of Baron's Mecha-Mooks tending to flowers.
SHIELD's Life Model Decoys in the Marvel Universe are meant to be completely indistinguishable from the people for whom they are body-doubles.
Doombots, programmed to act like the real Doctor Doom in his absence. Arguably, it's not very difficult to achieve perfect resemblance to the real thing when the template himself dresses like a robot with a hood and cape...
The resemblance is so perfect, various comic book writers have debated which appearances of Doom were actually Doombots. I.e., they're so good at impersonating Doom, even the writer of the story might not know it's really a Doombot.
Arguably justified to the point of deconstruction by Machine Man, in various Marvel Comics tales. The X-series robots are supposed to be, essentially, Terminators, but Abel Stack is convinced that a robot that can think as well as a human needs to think like a human; when the other fifty robots develop bizarre psychoses and X-51 remains sane, he's proven right, but X-51 also proves useless as a military device. Much later, in Earth X, Uatu the Watcher claims Abel made "Aaron" as an extension of himself, hoping to "live forever" in this way.
...And then Nextwave came along. Aaron Stack's 'sanity', even in the mainstream, can now be said to be somewhat suspect. Ironically, his increasingly 'robot pride' behaviour also came with him stopping to use anything other than his human name as he finds codenames and serial numbers demeaning. This personality shift is the result of a Heroic BSOD following his abduction and then abandonment by the Celestials at the end of his Dark Age series, X-51.
Both versions of The Vision from The Avengers: the original was married to the Scarlet Witch; the new one spent a year traveling around the world finding himself, likes to be called Jonas in private, and is now dating Stature.
The Vision's "brother", Victor Mancha, looks and acts so much like a normal teenager that he himself didn't know he was a robot for years. This was justified considering that he was built as part of an elaborate plot that required him to pass as human for a while.
DC's Red Tornado, who assumed the identity of John Smith, married a human woman and adopted a child with her.
The android Hourman, Matthew Tyler. He was even programmed with the 'geneware' of Rex Tyler, the original Hourman.
L-Ron, Maxwell Lord's assistant when he was running the Justice League, fits into this trope perfectly, as does Booster Gold's robot companion Skeets.
NYC Mech is set in an alternate universe where everything is exactly the same as in our world, except everyone's a robot. While these robots have have hair, they don't appear very human outwardly, with visible hinges and wires, but they eat, sleep, smoke, have sex, age, etc. That the characters are robots is so immaterial to the plot, one suspects that element was added at the last minute to give the series a unique hook.
The Metal Men are visibly robotic, and don't have human physical needs like nourishment, but are otherwise very much human in their emotions — in fact, they're each more emotional and sentimental than their creator, the stiff, dispassionate Dr. Will Magnus. This was an intentional bit of irony by writer Bob Kanigher.
Every droid created in the XXIII century in Paperinik New Adventures looks and feels exactly as a human. Despite that they are just treated as tools. This is later deconstructed when a Well-Intentioned Extremist droid tries to change history to make droids equal to humans. Later,with the "Droids Chart",they finally obtain rights.
