The character arc of is butchered in English. In the JP dub with English subs, the reveal of Masquerade’s identity is a gut-punch of psychological horror—Alice isn't just a host; she is a prisoner in her own mind, watching her body commit atrocities. The English version turns this into a simple "bad guy turns good" trope.
If you remember Bakugan fondly but think it was "too childish," you didn't watch the right version. Find the subs. Hear the real music. Meet the real Dan Kuso. You will never watch the English version again. Have you watched the Japanese dub of Bakugan ? Do you know of an active source for the English subs? Let the community know in the comments below. Until then, get ready for the brawl—the real brawl.
The answer, as many hardcore fans have discovered, is a resounding no. The original offers a radically different, darker, and more coherent narrative experience. If you have only ever watched the English version, you have not truly seen Bakugan .
