Kingdom Hearts 4 is one of gaming's most anticipated JRPG titles, as it begins a new saga in the long-running franchise. Kingdom Hearts 3 brought the series Dark Seeker Saga to a close, with its final events giving rise to Kingdom Hearts 4 and the beginning of the Lost Master Arc. Many believe the next saga to be setting up the Master of Masters as its big bad, but with the Lost Master arc delivering the first major shift in the Kingdom Hearts franchise, its trajectory and narrative are completely unknown. This has left fans guessing as to how and when the villain will make their grand entrance. If the series next era is anything like the Dark Seeker Saga, the big bad of the Lost Master Arc likely won't be revealed in Kingdom Hearts 4.
