And some random a$$ fan logic no one asked for:

-They can blush. Don't ask how, they just can.

-Everyone from the Hero Factory fandom can bleed. Though, their blood is black. But that also means that they can bleed to death.

-Yes, robots can cry. They cry normal tears, except for Surge.

-Although the heroes are considered "dead" when their core doesn't work anymore or destroyed, there are other ways for them to die. Such as getting stabbed in the "stomach", shot in the head, suffocation or just as mentioned above, bleed to death. There's probably more ways, but I'm not gonna list them.

-They do need food and water to survive, oxygen as well. And yes, they don't have actual organs. Fan logic.

-Don't bother asking about the having children thing. I have no flipping idea either (currently).
