I was thinking about Cybertronians the other day and how their body language would work, since they’re different from humans. I would imagine that eye contact isn’t something they’re big on for a number of reasons. 1) They spend a lot of time as vehicles and therefore don’t have eyes by our standards, 2) quite a number of them have visors, like Jazz, which would make eye contact rather difficult, and 3) the size difference would make it rather difficult for larger bots to look at little bots.
So eye contact would be something saved for things like face offs and persuasions/interrogations, when intimidation is important. Or maybe when they’re expressing extremely strong emotions. And this would mostly go for mecha without visors. Like Megatron and Optimus.
