Lan Paradinight (ラン パラディナｲﾄ Raan Paradinaito?) is a boss and assistant of Dr. Joe from Mega Man Ash. He was old friend of Neiha till from Megaman Ash 1, but in Mega Man Ash 3 when everyone in Neo Arcadia doesn't like him, so he wants to take revenge on them and then worked for Dr. Joe and has the objective of destroying Area Ash. In Mega Man Ash 4, he changed himself and became a good man by the help of Ash and befriends again with Neiha.
Lan is initially introduced as a selfish narcissist who places great emphasis on material wealth. Lan is not one to balk and retreat when faced with overwhelming odds in battle. A loyal, trustworthy ally who greatly values the ties of friendship, he acts like the 'big brother' of the group. He often provides comic relief; Neiha sometimes ridicules him for his comparatively older age, although he swears that his appearance is that of a mere teenager. His impulsive and brash nature has sometimes caused more trouble for people around him. Another flair he has is his ability to 'straight-talk' through many situations at hand. He believes that all things in the world (lives, dreams, etc.) can be bought and that becoming a Hunter will provide him with the necessary funds for his medical education. Despite his assertions that he is only after money, he eventually reveals to his friend Neiha that his dream is to one day become a doctor in order to help the poor. Lan was friend of Neiha till from only Mega Man Ash 1
In Mega Man Ash 3, when everyone didn't like Lan and send him out, he gets angry and even gets angry with Neiha. After he joined in Dr. Joe, he changed his mind and even protects Joe's 8 bosses which they are divided into the group named Hirokai-bots. Lan even becomes changed in the Mega Man Ash 4 by the help of Ash and befriends again with Neiha.
