Transformers One

Robots like to eat glowing square objects—their power cores that serve as their main course, along with snacks. They live like humans, only their appearance is different. Their bodies can sense feelings, and they even blush. They often engage in activities they're good at, or they go to what humans call a bar, but here it's called socializing: music and drinks.
