He needs more development. Why was he sent to Earth, and not any other alien? Why is he a coward? Does his species have any powers, and if so what are they and how does he use them, if he does at all? Are there other aliens on Earth? If there are no other aliens, how does he feel about that? How do humanity's actions compare to his kind's actions?

By making him an alien, you've essentially hit a goldmine for questions, most without answers. You could probably give him a ton of problems, if you wanted. Like, think of how he won't use any alien tech against humans even when threatened. It hurts to be a good person, so you could definitely build on that part of his character.
