Officer Heimdall was a former Augustgrad's citizen until he left for unknown purpose. Known as the oldest skater. He was first part of "Heroes Of Past" project. As a former navy officer, Heimdall needed only new equipment. Then he got hoverboard with additional combat side engines and customized scythe pistol. Additionally, Heimdall got in charge of Distraction Squad of United Earth Directorate and Earth's Syntraforce Department.

Gerard Dugalle's clone had to see new strengths and weaknesses of emperor Arcturus Mengsk. Then, with little help from officer Heimdall, the admiral found out a blueprints for Blackhammer. To find a way to stand up against enemy giants such as the said mech, Dugalle decided to order his engineers to built own gigantic mech. In result, there comes Syntraforce Reefbreaker, the counterattack against direct invasions on large scales.
