Which hero do you like the most based on their appearance?

Could you please elaborate on why a Warlock hero is incompatible with lizards? They both live in the Dungeon faction, along with hydras, dragons, and other reptiles. What should the hero ride then? A hydra? That would look ridiculous. Maybe a minotaur? No comment... But lizards are the most optimal option. And there is such a unit. Only regular warriors ride regular lizards, while heroes ride major ones. Regarding mages, do they live in the sky? I'm hearing this for the first time. They actually live on the ground. It's just that their cities are built in a strange way, but that's a minor detail. Maybe they have a portal there.
