Cosmi is a huge worrier. He always thinks the worst is going to happen, because it usually does. Umm..It’s not that bad actually.
Cosmi is the closest to Roi. He genuinely likes Roi and feeds of Roi’s optimism. But, because Roi is SO easily tricked into doing things it makes Cosmi lazy. Cosmi is usually the one most annoyed by their situations. He’s quite angry at times that things never seem to go right for them. Despite this, he really cares for his crew mates and would do anything to save them.
Cosmi is also prone to taking short cuts with things, even if it causes trouble for other aliens they meet. This is something he and Henge clash about, so Cosmi tries to keep Henge in the dark about it.
