Dst is the abbreviation of a toy company in America. The full name is Damon's selection of toys. Marvel Comics authorized a 7-inch scale doll series for dst. This 7-inch Marvel comic series is called Marvel Select.

Hasbro is also an American toy company with a larger scale and more series. Marvel Comics authorized Hasbro to make a 6-inch doll series. This 6-inch series in Marvel comics is called Legend of Marvel Comics.

From scale to joint design, the differences between the two companies are obvious. Strictly speaking, there is no special relationship between the two toy companies, that is, they are both making toys in Marvel comics.
