King Terask
A giant red dragon in NeoQuest II who has taken over Faerieland, part 5. The first time you fight him, he has 2,500 hp, powerful attack, and magical abilities. After you have beaten him, he later resurrects as the final boss, with 5,000 hp, extra magical abilities, etc. By beating the second one, you get a Trophy, random Rare Item (options depend on the game level), and 10,000 NP, I'm told.
