Elemental Fusion (Marvel Cinematic Universe)

The Elemental Fusion is the climax antagonist of the 2019 film, Spider-Man: Far From Home.

Overview
After all four Elementals were defeated in the first half of the film, Quentin Beck (aka Mysterio) wanted to create an Avengers-level threat to cement his reputation as a "hero". The Elemental Fusion appeared in the climax, when Beck summoned all the Elementals and merged them together via the illusion drones that were designed by him and William Ginter Riva. The Fusion then proceeded to wreak havoc across Berlin, and Beck sent his Mysterio suit to battle it. Spider-Man arrived on the scene and, knowing what a phony Beck really is and that the Elementals were illusions, he immediately dismantled the Fusion, forcing Beck to kill the illusion. It never appeared again after that.
