Well, for one, his dialogue would be full of Italian phrases and idioms. He might be more flamboyant in his expressions. Since Italy has a rich cultural heritage, he could bring elements of that into his conversations. For example, he could talk about Italian architecture or literature. His Italian - speaking self could also be more of a mystery, as it gives a new layer to his character. The fanfic author might use his Italian language skills to create new plotlines, like him having to deal with Italian vampires or using his language to woo Bella in a different, more exotic way.
Well, start with AO3. It has a huge collection of fanfics. Just type in 'Edward Twilight Italian speaking' in the search bar.

Edward in the 'Edward Tumor Twilight Fanfic' might be portrayed with some unique characteristics. Maybe he has to face the challenges brought by the 'tumor' aspect in a way that is different from the original Twilight story. It could add a new layer of complexity to his character.

Some popular 'Twilight Edward and Bella Fanfic' include 'A Glimpse Beyond Twilight'. This fanfic gives readers a chance to see what could have happened after the events of the original series. 'Edward and Bella: Unseen Moments' is also great as it reveals some of the unshown moments between them. 'Twilight Fanfic: Edward and Bella's Love Redefined' is another good one, as it redefines their love in a more complex and interesting way.
Maybe it's because of a past traumatic event related to water that happened to him. Or it could be a supernatural reason specific to the fanfic's alternate universe.
