Worldwide character rights to 'Valentine' are held by Skylar Comics and their film division Skylar Pictures. The character was an original comic creation of Skylar producers Sarjono Sutrisno and Aswin MC Siregar and artist Ian Waryanto. Note that despite the words "Dark Avenger" being included in the full movie title, the character (and studio) are in no way linked to "The Avengers", a character mark held by Marvel Comics.
Valentine is the newest comic drama-action genre from Skylar Comics.
The Valentine comic story idea emerged from Sarjono Sutrisno who was
later developed by Aswin MC Siregar. The picture in this comic was
entrusted to Ian Waryanto and the coloring by Warnia K. Sahadewa who
had previously helped with the previous comic Skylar Comics project.
