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.
Complete Monster: There have been quite a few, but Empera Seijin and Ultraman Belial certainly count. Belial moreso in that while Empera's attempted crimes were on the same score as his, Belial's were against his own species. What else could describe a being who'd steal the sun of his home world and leave it to turn into a frozen wasteland with everyone on it? This was AFTER he killed the being who had fought his way into the space-prison where Belial was held, broke him out and gave him an artifact of power, and began essentially licking his boots.
Crowning Moment of Heartwarming: Seiji and Yuuko's reunion and Ultraman 80's reunion with his students in Ultraman Mebius. The fact that the brought all the original actors back to reprise their parts makes it all the sweeter.
Fridge Horror - Zetton (and its successors) look more cool than scary. Supply material note that those boxes that appear to be its eyes are actually the ears. So where are Zetton's eyes? Those glowing spots on its chest. Suddenly, the beast look much more creepy than before.
