Loki / Thor
The two of them had different styles of fighting, which was probably why if they ever got their shit together and fought for the same purpose, they'd be unstoppable. Loki had abilities that went far beyond what Thor could do, and vice versa depending on the situation at hand.
Thor was in his element now. If ever there was a reason for him to be arrogant, it was his ability to rush into battle and actually make shit happen. Even if he'd failed to kill Thanos, he'd taken down plenty of his army. Before that, years ago, he'd gone into battle for the most foolish of reasons at the Jotunheim but he'd dealt plenty of damage there too. He didn't know how to navigate his grief, but put him in battle and he knew exactly what to do.
As Loki assessed, Thor was doing much the same. No, these aliens weren't physically very strong but their weapons were definitely lethal. He'd managed to counter some sort of energy ray with a bolt of lightning but he was sure if it had hit a person they would've been obliterated. "Loki, have you seen this race of beings before in your travels? I have not," he called out to his brother. He dove downward in in a burst of lightning and took out another grouping of them.
