A thin but tall Falleen, Nerrax has a light, mottled, green skin, a rigid head and dark hair which he wears in a tightly knotted low ponytail. His facial features are somewhat soft and while not ugly, he also isn't considered particularly handsome. His face is smooth and hands contain almost no calluses, and the combination of his accent, appearance and clothing betray an upper upbringing.

Nerrax Zim is dressed smart. Wearing a nicely decorated, but practical thick woolen cloak in House Zim's colours, green and golden, the young noble certainly looks the part. Wielding a small, ornate obsidian staff adorned with jagged blood-red crystals, the young noble's gait is one of confidence and his gaze is observant but cold.
