Once again Optimus Prime and Megatron were re-engineered, with Prime now a fire truck and Megatron a six changer, whose modes included a dragon, bat, jet, land-craft and a giant hand. Another G1 character to get a new toy for this line was Ultra Magnus, who could combine with Optimus Prime to form Omega Prime. Other combiners were created for the series too, such as Landfill and Rail Racer. Bruticus, a combiner from G1 was also recoloured and introduced into the series, with a coinciding toy re-release. The Combaticons that formed Bruticus were the first of the Decepticons to be introduced into the show along with Scourge, who as a toy was a black repaint of G2 Laser Prime. These were not the only toys to be re-released for this series, with many from past lines being repainted and packaged in RID boxes. Robots In Disguise was responsible for introducing a lot of concepts that would be re-used often in the next incarnations of Transformers.
