Fairy Tail GMG summoning

Synopsis:

During Lucy's intense battle against Flare Corona in the Grand Magic Games, her desperation and magical instability inadvertently tear open a portal to another anime universe. Through this rift emerges a powerful and malevolent character who sees an opportunity in this new world. Their arrival dramatically alters the course of the battle, Lucy's development, and the fate of Fairy Tail and all of Ishgar.

Summary:

The story begins at the crucial moment of Lucy's fight with Flare. As Lucy pushes her magic to its limits, a sudden surge of energy creates an interdimensional tear. The malevolent character (let's call them "The Intruder" for now) steps through, immediately assessing the situation and seeing potential in Lucy's raw power and the magic-rich world of Earthland.

The Intruder intervenes in the battle, defeating Flare but also manipulating Lucy's magic and mind. This sets Lucy on a darker path, struggling with new abilities and influenced by The Intruder's corrupting presence. Meanwhile, The Intruder begins to quietly manipulate events behind the scenes, setting larger plans in motion.
