Variations

Each M10X came with a detachable chest piece. The chest pieces were the same as the "barefoot" series.  The chromed chest pieces were carry over legacy from the Henshin Cyborg. Microman M10X chest pieces were not randomize but specific to each member.

Microman M10X Type had several variations and production run changes.

1974 Release 1 - Founder Series or First Series Microman.  These early Microman figures were similar in many way to M10X but they did not have 5mm port and they came with barefoot design.  The first version had metal tab instead of the rubber tube to hold together the arm sections.

1974 Release 2 - Takara replaced the metal tab design with the rubber tube.  The first two released were sold only as part of Microman Kit-Machine toys.

1974 Release 3 - Takara sold the figure separately in white capsule. The early capsule was similar to the later 1975 capsule but the lid had extra engrave details and the bottom capsule tray had two plastic tabs to hold the figure in place.

The first three releases actually were sold as Clear Microman, Yellow Microman, Blue Microman and Orange Microman.  These naming convention came from the Cyborg since Takara would called each Cyborg by their inner part color such as Silver Cyborg 1 or Gold Cyborg 1 etc.  Microman naming and numbering convention were not introduced until the re-launch of the line in 1975 in which Microman became their own toy line and no longer just miniature version of Henshin Cyborg toys.

1975 Release 4 - Takara introduced 5mm port to the original series Microman and replaced the barefoot with M11X style cybernetic shoe. The short cuff style was also change to the common long cuff style.  

1975 Release 5 - By mid 1975, Takara also changed the short shoe to the longer type just as they changed the M11X type shoe to the longer type.  The early version shoes were too short and made the figure difficult to stand and pose. 

1976 Release 6 - Takara added the word "Japan" to the back just above the 5mm port.  This was probably done to distinguish M10X from Mego Micronauts version. Takara also changed the design of the capsule sticker from the green badge design to the Microman Command style logo.

1978 Release 7 - In 1978, Takara began to use semi-opaque white shoulder part for the figures.  Some of the early Microman figures that became out of stock in 1978, like the M10X, M11X and M12X, were produced with the new semi-opaque part.  The semi-opaque shoulder parts would became common for most of the New microman figures.  Takara also changed the color of M103 from dark cobalt blue to lighter sea-blue color. 

 Also added to 1978 version were the small holes on each side of the legs. The hole was design for the Rescue Power Up Accessories.  Takara released two set of Rescue Power Up accessories in 1979 and one of the set even came with two new members of M10X (in smoke clear and clear green).  Takara planed several more Power Up accessory which would take advantage of the holes now common to most Microman figure since Command series but the Power Up Series was cancel along with the Original Microman line in 1980.

In 1976, Mego licensed Microman toys from Takara and released copy version of M10X as Micronauts Time Traveler.  Mego version had few differences from Takara Microman version.  Mego Micronauts came package on a blister card without the capsule.
