So for all my complaints, Thanos is awesome in Infinity War.

I'd say a good approach for Darkseid is too keep in mind he's worshiped as a god. Playing off that aspect would work well. Show that his followers love their leader.

And highlight his lieutenants. The Black Order was cool but sadly got taken out after only one movie. Show off Granny Goodness and her Furies. Canto. Kalibak. Vermin Vundabar.
