Currently, there seem to be no plans for Elemental Hero Synchros. But card games change and revolutionize themselves all the time. While unlikely, it is impossible to state that there will never be an Elemental hero Synchro Monster.
Yah he's right...But wouldn't it be awesome?
The whole point of Elemental Heros is to fusion, synchro would not make any sense and plus with these new elemental heros I don't think they need a synchro monster anyways XD
