User blog comment:AustinDR/The Villains I Dislike/@comment-31599322-20180511181447

1. Tamatoa: don't know.

2. RWBY: as you stated, RWBY's villains are very generic.

3. Grings Kodai: I'm not a big fan of Pokemon, however this guy seems to be a real douche.

4. Malekith: don't know (not a big fan of the MCU, either).

5. Steppenwolf: oddly enough, I liked him despite his lack of backstory and evil motives. However I do not think he is "weak"; ok he was fairly easily defeated at the end, but do not forget that he invaded countless planets and fought legions of warriors and even divinites with his "bare" hands before being defeated on Earth. Even so, he remained a powerful and fearful conqueror till the end.

6. Mei Aihara: don't know. However after a quick examination she seems to be another generic, abusive "lover", and, as you said, she "sets a bad example of what a yuri manga is supposed to be, and that it unwittingly advocates abusive relationships", despite her tragic backstory.
