You can barely see the number 1 behind her and I know she's out of proportion but I don't think she's majorly off. Btw, this is NOT the FiM Rainbow Dash as that one didn't exist when the card this is used on was created. Card info:
My Little Pony Force I - Rainbow Dash
LIGHT/Core 7 Pony/4/ATK 1600/DEF 1200
You can Special Summon this card when you control "25th Anniversary Celebration". If you do, it cannot attack this turn. When you summon this card, flip a coin: - Heads: While this card is face up on the field, it gains 500 ATK for every "My Little Pony" monster you control - Tails: When this card battles, its ATK is halved during Damage Calculation.
