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.
In a sense, Constantine. Sure, he is a bad guy, but Kamikazi mistreats him very badly, and on some occasions he is shown to be nicer than his boss, such as "Teasebots". Also, in "Kamispazi!" it's implied that he grew up at an orphanage. If that doesn't make you want to hug him, nothing will.
Tommy too, especially in "I Want That Toy" and "Crying Time".
