## Trivia

* With the exception of E6 + E3, Black Shinkalion Ogre X Kurenai, the Trinity Combination, the majority of the Z Combinations and Dark Shinkalion Double Z, most combinations featured in Shinkalion media have involved a unit based on the E5 series.
* The Z Combinations are similar in concept to the Synchro Fusions from the Tomica Rescue Drive Head series, though aside from similar parts separation (the arms and legs of both the Z Units and Drive Heads separate from the body in the same places) the execution is vastly different between the two.
* The *Change the World* combinations bear similarities to most form change gimmicks from *Kamen Rider*, a franchise with a master toy license firmly with TakaraTomy rival company Bandai. Specifically, it represents the vast majority of most form changes in the series, which typically only uses one additional unit at a time.
