Kenner Action Figures
In 1993, Kenner met with Greg Weisman and pointed out their main concerns for the toy line included (among others) that there was a lack of significant vehicles for both the protagonists and antagonists, that the Trio and Bronx didn't look heroic (i.e. aggressive) enough, and that the key human ally (Elisa) and key evil gargoyle (Demona) were, in fact, both female.

According to Greg Weisman, Brooklyn was supposed to have a special feature inside his jaw, which distorted his head and neck. Ultimately, the special feature was considered too expensive, but the figure's head and neck remained off-model.
