Crown Thunder (クラウン・サンダー?) is a character from the Mega Man Star Force series. He is the EM Wave Change form of Crown and Jean Couronne XIV.

Game History

Mega Man Star Force

He is an optional boss in the first Star Force game. He shows up in the Dream Island junkyard. His compatible human is a dead human king called Jean Couronne XIV. He died long ago, but his ghost remained and was able to EM Wave Change with Crown to become Crown Thunder.

Anime History

Shooting Star Rockman

His origins are the same as his game counterpart, except he appears in an abandoned amusement park. He is defeated by Geo Stelar and Omega-Xis. Later when Cygnus Wing steals an EM wave device, Crown can become Crown Thunder again and he could turn into his human host which is a corpse pierced with arrows. He is a huge fan of Sonia Strumm, and watches her drama show and concerts with Cancer Bubble. In an episode where an EM wave comet passed by, he gained the ability to fuse with dinosaur bones. He was still defeated by Mega Man and lost this power when the EM wave comet passed.

Crown Thunder and the other FM-ians attack Earth in a desperate attempt to fill the Andromeda Key with negative energy. But, they retreat when Cepheus sends a message telling them to return, however they decide to stay for three more days before returning. Cancer and Crown are going to Sonia's concert when they are attacked by Gemini Spark. Crown covers Cancer's escape and is killed by Gemini.

He also appears in the last episode of Shooting Star Rockman Tribe with all the FM-ians and their compatible humans.
