Atomic is the fourth Gormiti toy series to be released in Italy, where it followed on from Mythos and Series 2. In the UK the Atomic Series was the third series released, after Energheia and Series 2. The Atomic series represents an "evolution" of the Series 2 toy designs, supposedly after each tribe unlocks a special atomic power. In practise, the Atomic series toys were all repaints of the Series 2 molds. The Atomic series also introduced gimmicks, which would go on to be something of a series hallmark.
