Anime's biggest franchises are in full costume. My Hero Academia, Frieren: Beyond Journey's End, Oshi no Ko and more rolled out spooky Halloween makeovers for the holiday, ComicBook reported Saturday.

The seasonal art drops have become an annual ritual: official accounts and studios reimagine their casts in Halloween dress, giving fans shareable images and keeping series visible between episodes and seasons. This year's batch leans into the holiday hard, with TOHO Animation's Frieren artwork among the standouts circulating on Friday.

For shows like My Hero Academia — deep into its run — and newer hits like Oshi no Ko, the makeovers double as a pulse check on franchise momentum. A series that gets fresh holiday art is a series its publisher still considers worth promoting.

The Halloween celebration spans well beyond these headliners, with studios and franchises across the industry posting their own seasonal pieces throughout the day. For fans, it's a once-a-year gallery of favorite characters in their spookiest looks.
