A powerful swordfighter on a journey to find the dragon's treasure. Before joining this group, he has already killed a young green dragon with a party of six. The Fighter has the second strongest attack power. His range and speed easily outperform the other shield-carrying heroes (Cleric and Dwarf) and his jump is faster and higher. Derek gains HP the fastest and his speed can make his defense almost as good as the Cleric's. The main thing he lacks is magic, at which he is the weakest.
