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.
A plot where the relationship between the bride and the Titan she is married to develops in unexpected ways. They might start off as strangers, but as they face challenges together, like dealing with other Titans who are not accepting of their union, they grow closer and form a deep emotional bond.
Another plot idea could be a love triangle within the Titan world involving the bride. There might be a powerful Titan who is jealous of the relationship between the main Titan and the human bride, and this jealousy could lead to a series of events that put the relationship and the Titan society in jeopardy.
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.
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.
