- Sireen is a Micromaster from the Operation Combination and Micromaster Collection portions of the Generation One continuity family.
Sireen is a member of the Turbo Team, six urban-operations Micromasters who can combine to form Sixturbo. The Turbo Team fight alongside the Guard City team and other Micromasters to protect the Earth from the forces of the mighty Decepticon führer Scrash.
In an alternate-timeline/universe, Sireen is an Autobot Micromaster who serves the interesting dual functions of medic and strategist. He is outfitted with an overhead storage rack for miscellaneous medical equipment (which looks suspiciously like a pair of guns). Sireen is reportedly a longtime friend of the Autobot Micromasters' other strategist, D-Go of the Sixliner Team.
(Note: Since the Sireen of "Operation Combination" had no bio information whatsoever, it is unknown if the "Micromaster Collection" bio is retroactive, applying to the original version as well, though many fans treat it as such.)

Sireen never appears as an individual, only as a component to Sixturbo's robot mode.
Micromaster Collection Story
Sireen was the only member of the Sixturbo Team who was not originally infected by the Reverse Evolution virus. He and Joe developed an antivirus program to return the other Sixturbo Team members to normal. In order to get the program into their systems, Sireen surrendered to the others and convinced them to combine into Sixturbo, activating the program just as they combined. Sireen was briefly turned into a Decepticon himself just before the antivirus program took effect, turning all six components back into Autobots.
After this incident, Sireen modified this antivirus program to create the Vaccine Program Gun, which would theoretically do the opposite of the Reverse Evolution virus, turning Decepticons into Autobots. However, not only did the weapon fail to work as intended, but it had the unexpected effect of turning Sixwing into Berserker Sixwing.
- Sixturbo (Micromaster Sixteam, 1992)
- Japanese ID number: TF-03
- The original version of Sireen was available only as part of a Sixturbo gift set in Japan. Aside from the ambulance mode, Sireen can form either leg of any of the similar-build Six-Teams (Sixturbo, Sixbuilder or Sixwing). The original Six-Teams are considered among the more difficult Japanese Generation One pieces to find.
- The connector socket for Sixturbo's foot-plate is approximately 5mm wide, making Sireen compatible wiith Powerlinx plugs, though the placement is awkard in most instances.
- Sireen (Micromaster, 2002)
- In 2002, the entire Sixturbo team was re-released as part of the "Micromaster Collection", in individual boxes with a number visible to show which mold was inside each box. For this release, all of the decals from the original version were replaced with paint applications. Sireen came with the right foot to Sixturbo in this release.
- In every case of twelve Turbo Team Micromasters, two of them were solid-black-plastic "Reverse Evolution" Decepticon-allied variations. All six Micromasters were available in this manner.
