Dashiel "Dash" Parr is the son of Mr. Incredible and Elastigirl. Dash has super speed and constantly wants to use it but his parents want him to hold back so he doesn't give away he has powers and reveal their identity.

I think both play Dash has an energetic kid really well. However, Spencer got to show more of Dash's personality while Raymond had to focus more on the energy (though he does sound a lot like Spencer).
I will go with Spencer Fox but Raymond was a good stand in.
