I'm voting based on the originality of the design and how much I liked it. Abilities are harder to evaluate, so I'm not considering them.
1. -
2. I don't really remember anyone from there, but the unicorns look decent.
3. There are many memorable creatures, but the highlight of this game is the "Eyeball". It's hard to find a funnier, yet grotesque creature; it's excellently designed. However, if we're talking about something impressive in a good way, then it's more likely one of the dragons, with their impressive power and attack/flight animation, which perfectly emphasizes this. In this regard, the golden dragons look the best (but the audience award still goes to the female warriors on pegasi).
4. Dragon-golems. In the fourth game, I don't like many of the creatures' designs, but these guys are a top-notch idea.
5. Angels. The best angel design in the entire Heroes series. Of course, archangels and seraphim also look interesting and impressive in their own way, but I prefer the non-upgraded creatures. I would put ancient ents in second place – many people don't like them, but I was impressed by their tall, yet aggressive design.
6. Enhanced Luminaries. In general, the developers of the sixth game should be criticized for constantly exploiting the image of elemental girls in various forms. On the other hand, this is what they did best.
7. Although the game and the faction compositions look stylish overall, I now realize that there isn't much good to say about individual creatures. Well, the genies were pretty cool.
