Modulok was introduced into the Masters of the Universe toy line in 1985, a little after the first wave of [[Evil Horde]] figures.<ref>https://www.cbr.com/he-man-strongest-villains/</ref> His figure was an instant hit with buyers due to its unique nature. The figure came packaged in a cardboard case, its 22 pieces encased in a plastic bag within. These pieces include two heads and numerous arms, legs, a torso and tails which can lock together in seemingly endless ways. Some of the body parts are more human-like while others have claws and are more monstrous in appearance. There are even enough pieces to form two separate monsters. The toy came packaged with the mini-comic "[[The Treachery of Modulok]]" which showcases the character and his abilities.<ref>{{cite news|title=8 Crazy Masters of the Universe Figures |work=Mania.com |date=2010-04-08 |url=http://www.mania.com/8-crazy-masters-universe-figures_article_117840.html |accessdate=2009-11-20 |deadurl=yes |archiveurl=https://web.archive.org/web/20091001163220/http://www.mania.com/8-crazy-masters-universe-figures_article_117840.html |archivedate=2009-10-01 |df= }}</ref> He is introduced as a former slave of [[Skeletor]] who escape Skeletor's clutches and offers his services to the Evil Horde, knowing of [[Hordak]]'s personal hatred of Skeletor. Together with Hordak, he proceeds to concoct a scheme involving his body parts being sent, one by one, to the Royal Palace of [[Eternia]] in separate cardboard boxes, labelled as presents to the members of the Heroic Warriors. Confused by the numerous body parts being delivered to the palace, [[Man-At-Arms]] suspects the forces of evil may be behind it and sends [[Prince Adam]] and [[Teela]] to [[Castle Grayskull]] with the body parts to ask [[Sorceress of Castle Grayskull|The Sorceress]] about the creature. As they speak to The Sorceress, she informs them of the identity of Modulok, Modulok reforms himself and uses his shape-changing abilities to steal a forbidden weapon from the Castle. A battle then ensues involving a clash between [[He-Man]], Skeletor and Hordak, in which Modulok showcases his shape-changing abilities, including his ability to split into two separate beings. A later appearance in the mini-comic "The Menace of Multi-Bot" showcases Modulok as a scientist, tying in with his role in the cartoon series.
