I do like how hands-on Steppenwolf looks in this

Obviously they're building up to Darkseid like the MCU has been with Thanos, and Steppenwolf does has a similar function as Loki did in The Avengers as they both serve their masters respectively, but Loki was just a lackey/another minion really to Thanos. I know Steppenwolf is Darkseid's uncle, but just from what I know about the two characters, it seems like Steppenwolf is more of his own entity from Darkseid and could probably even match him in battle. I know he has the parademons for the invasion, but just from the trailer, Steppenwolf looks really hands-on, going up against each member individually, especially Wonder Woman and Aquaman, which I'm excited to see, because in the Avengers Loki was mostly overseeing his own invasion rather than going up against each Avenger individually. So I like how they're taking that approach with Steppenwolf.
