In 2017, Hasbro transitioned the prior Titans Return toy line to the new Power of the Primes Transformers toys. This toy line featured “Prime Masters” rather than the prior Titan Masters. These Prime Masters represented the sparks of the Primes and had decoy armor, similar to Pretenders of the past. This line featured combining transformers which were compatible with the prior Combiner Wars figures. Otherwise, this line is known for its heavy use of decals instead of paint for details.
