Mini-Cons are (perhaps paradoxically) big again.The concept, first introduced in 2002 with the beginning of the Armada franchise, became a major addition to the Transformers mythos for a few years, but fell into only intermittent use in the years after the so-called "Unicron Trilogy" (of which Armada was the first part) ended. They have returned in the past couple of years as a significant feature of the 2015 Robots in Disguise line (Henceforth abbreviated as RiD. This line is still current, but I mention the year it started to set it apart from the original Robots in Disguise line of 2001).
