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.
The Scrappy: Han. The hate comes from the fact she took part in beating Honse and she's a little too loyal to Vera.
Shinra's widely hated for her bitchy attitude.
Villain Decay: Sort of. Earth Beast is introduced by having him kick Gangryong's ass. Then we promptly find that he's The Load of the Heavenly Five Paths because the chain of his martial art has been broken, possibly forever.
