How about Mertil? I know, technically not a civilian, but he had it pretty rough. Lost his tail, can't morph to get it back, has to live in hiding on Earth, and then his caretaker/bestfriend/shrom/soulmate(?) dies of an Andalite equivilent to cancer, and he's left alone. In a human house that probably doesn't have the full morgage paid off, and will probably be reposessed at some point.
Even after the war, once Andalites are more well known, he'd still be shunned BY the Andalites for being a vecol. And there's no mention of Marco making good on his promise to hang out with him.
