UltraDuck

UltraDuck (スーパーマラード, Sūpā Marādo, or "Super Mallard") is a fanfiction anime by LDEJRuff. Based loosely on Superman, it tells the story of an extraterrestrial duck from another planet who plans to save the world and fight for truth and justice.

Synopsis
The majority of the story takes place in the fictional city of Megatropolis (メガトロポリス, Megatoroporisu), where mild-mannered humanoid mallard Drake Duck (ドライクダック, Doraiku Dakku) works as a local newspaper reporter. After traveling from his home planet of Colverterra (コルベルテラ, Koruberutera) as a duckling, he unknowingly gains many supernatural powers.

Unlike in Superman, Colverterra neither was under attack nor exploded. Instead, Drake was drafted from Colverterra by his biological parents after they knew that Earth needed someone to protect it.

When Megatropolis is in danger, Drake becomes UltraDuck to save the city and become a hero.
