Mars Power, Make Up

The opening entry in Rei Hino's transformation sequence, Mars Power, Make Up, carries her into her Sailor Mars identity across the manga, the animated series, and Crystal, and it stands as her sole transformation throughout the live-action production. In every telling except the live-action, it eventually upgrades into Mars Star Power, Make Up.

The manga handles it plainly, with Rei lifting her pen, speaking the words, and shifting into Sailor Mars at once. The anime elaborates, as she holds the Transformation Pen to her chest and long ribbons of flame stream out and drop as fiery rings that cinch around her to form the whole costume before she lands her familiar pose. Crystal frames her against the red planet, the pen releasing bright rainbow light as her nails turn red and a purple silhouette takes over, fire spiraling around her until she spins to reveal the finished uniform and the Mars sign on her brow. The live-action take runs longest, her Jewelry Star Bracelet unsealing into full form while glowing gems, reddened nails, lengthening black hair, drifting flower petals, and a materializing bow each add a piece of the outfit until flames and her symbol flare behind the completed stance.

Rei Hino is the only one to use the command. Her Transformation Pen drives it in the manga, anime, and Crystal, whereas the live-action series swaps in the Jewelry Star Bracelet. Notably, although she becomes Sailor Mars back in Act 3 of the manga, she does so there without ever speaking the phrase, and in the live-action series she is the sole guardian whose hair color stays the same during the change.
