【MAD】Return of Ultraman 帰ってきたウルトラマン by Ken Fujii, The Blessin’ Four & Land of Light Children’s Choir 

"After most of the Ultra Warriors which have defended earth throughout the so called, "Showa Era", have returned back to Nebula M78, Land of Light. Ultraman proposes an idea to Ultraman King to showcase each Ultra's backstory and their songs sung by earthlings. Ultraman King accepts the proposal and hosts a meeting to settle the ideas with other Ultra Warriors which they agreed with the idea. The first Ultra Warrior to be showcased is "Ultraman Jack", formerly known as "The Returned Ultraman". An Ultra Warrior who fused with a human, received a weapon from Ultraseven, was sent to earth in order to chase down monsters and fight alongside humanity to protect earth!"
