I got my name from the fact that as a person I could be very loud, also because I want my pony self to be a strong stallion but I still haven't figured out whether I want to be a pegasus or an earth pony here is why:First being a pegasus would mix well with the name because you know it has thunder in the name but then if I was an earth pony my name would be like a metaphor for how I am so strong that a hoof punch is like a thunderstrike.
