I think that Starscream also has those emotions at the moment. Puny humans shouldn't have such tech!(besides they don't know that his suit is the only one)

The main problem of any Transformers/Iron Man crossover is that in both original series, it's follow ups and movies kybertronians are displayed underpowered(to show the scenes where usual armed forces can hurt them) while in both comics and movies Iron Man is overpowered beyond any limits leading to the situation where with exception of Heavy-framers like Megatron and Optimus, everyone else is cannon fodder that won't even pose a challenge.
