To me it's--



Starlight Glimmer - Twilight Sparkle

Sugarcoat - Rarity

Indigo Zap - Rainbow Dash

Sunny Flare - Fluttershy

Sour Sweet - Pinkie Pie

Lemon Zest - Applejack

Trixie - Sunset Shimmer

Flash - Spike (Flash was a G1 Dragon from the late 80s. Despite not being in G4, I just want to include him as a yellow-and-orange version of Spike, who is purple-and-green)
