Sunstar

Sunstar, known as Sungod (サンゴッド) in Japan, is the final boss of Mega Man V. Sunstar is a ancient doomsday weapon from the same era of the Stardroids that was found by Dr. Wily. After his defeat in Wily Star, Wily activates Sunstar to defeat Mega Man. Sunstar attacks Wily, but fights against Mega Man anyway, saying that robots were created to fight and he must destroy all inferior forms.

When Sunstar was defeated in the battle, Mega Man asks if he is alright and wants to take him for repairs in Light Labs. Surprised with his kindness to an enemy, Sunstar asks why he's helping him, as both are robots created only to fight. Mega Man says he's wrong, and that he will only fight when it's needed to protect the world, and robots and humans can live together in peace. Sunstar thinks about what Mega Man said, but says he will never know as his fusion reactor was critically damaged and it could explode at any moment, and asks Mega Man to leave. Shortly after Mega Man's escape, Sunstar's explosion destroys Wily Star.

Sunstar has a great variety of attacks, and his Nova Attack is extremely powerful, but Mega Man can counter with the Spark Chaser as it can hit Sunstar multiple times.

Trivia

 * Sunstar's name is derived from the Sun.
 * The reference to brushing teeth in Sunstar's data is probably a reference to its status as an early-morning activity. It makes sense that Sunstar would enjoy things done as the sun comes up.
 * Sunstar bears a resemblance to Pharaoh Man
 * Currently, Sunstar is the only final boss from the classic series games who isn't Dr. Wily.
