The Avengers would be shocked at first. Tony Stark would probably crack a joke about 'giant naked monsters' while quickly analyzing the threat level. Captain America would be all business, immediately assessing the situation and trying to figure out how to protect civilians. Thor would likely see the Titans as a worthy foe and be eager to engage in battle, swinging his hammer with enthusiasm. Hulk might just charge at the nearest Titan without much thought, seeing them as something to smash.
The Teen Titans would react with a combination of fear and courage. Starfire, being from another planet, might have some knowledge about the invaders which could be useful. But she'd also be worried about her new home, Earth. Cyborg would probably be excited to take on the new technology of the aliens, seeing it as a challenge to improve his own. Raven, on the other hand, would be more cautious and try to sense any dark motives behind the invasion.
Robin would probably be very hurt. He might initially go into a state of shock and disbelief. After that, he could try to find evidence to prove his innocence. For instance, he might search for surveillance footage or eyewitnesses.
It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
Starfire would be overjoyed. She's always been the emotional and positive one. She would probably throw a huge celebration for them, with lots of alien delicacies and bright decorations. She might also give them some advice about love based on her own experiences with Robin.
Well, considering that Titans are mindless creatures in most cases, they may not have a very complex reaction. They would likely see the Transformers as large, moving objects and target them as they would any other large target. But if the Transformers were to use their advanced weaponry and abilities, the Titans might be deterred. For example, if a Transformer used a powerful energy blast, it could make the Titans hesitate or retreat. Also, the Transformers' ability to transform might puzzle the Titans and disrupt their normal behavior patterns.
