Without any on-packaging bio or animated or comic book stories to give any context, it's hard to say why this Railbot is named Swindle. He does not seem to be a version of the classic Combaticon con-artist from G1, so we're left to assume he's some sort of fast-talking Autobot. He turns into an EF66 locomotive, and part of the Railbot team. This figure was available earlier in Japan under the name Night or Convertor. His Universe version came out in 2005 exclusively at KB Toys.
The combined form of the Universe Micromaster Aerialbots is Superion, an amalgamation of six robots plus their pack-in accessories that serve as connectors, head, and extremities of the gestalt warrior. While in Japan, the original source of the design ( Sixwing , 1992) was available in a collected set, this combiner needed to be purchased one bot at a time in the 2007 Universe release.
