These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Everybody but Japan loves New Century: New Century was a commercial flop in Japan, but when it was exported to the U.S. it was far more successful, doing even better in television ratings than Chaotic Century did.
Fanon: Quite popular, usually in the form of connections between New Century and Chaotic Century. For example, it's commonly accepted that Liger Zero is a further evolution of Van's Blade Liger and Zeke, and less commonly believed that the Berserk Fury is similarly Raven's Geno Breaker and Shadow, despite neither even being implied in the series. The red Blade Liger is also believed by some to be Van's Liger and Zeke, if the Liger Zero isn't.
