Molly

"If she dies, the dream she made for her planet will die. And no one will know her sacrifice."

- Shadow

Molly is a girl seen in season three of Sonic X, having a one-time appearance in episode sixty-eight. She hails from a nameless planet ("Cascade" in the English dub) where she is rescued from the Metarex by Shadow. Shadow notes how much she reminds him of Maria Robotnik and witnessed her sacrifice herself during a Metarex attack. Shadow then built a memorial in her honor, and is seen standing by it in the final episode of Sonic X.

Cascade Resistance
It is believed that Molly's world, a planet with an empire throughout space made by ruthlessly attacking and conquering other worlds, were at war with the Metarex and various other species throughout the galaxy long before the Metarex's transformation into cyborgs, judging by how the enemies of Cosmo's people used the same type of aircraft in battle Molly's people used. As a result of this, the Metarex took the Planet Egg from Cascade, reducing it to a lifeless and literally broken world.

For generations afterward, Molly's people continued to fight the Metarex as a resistance, their numbers becoming fewer and fewer all the time.

One battle involving roughly a dozen resistance troops (with Molly among them) fought against the Metarex in space, almost getting wiped out in the process. Nearby, Dr. Eggman was searching for a Chaos Emerald in the sector they were fighting in and his ship was receiving damage due to the battle. He sent out Shadow to defeat the Metarex and he ended up saving Molly while she provided a distraction for the remainder of her team to attack the mother ship. With Shadow and Eggman now involved in the fight, the Metarex's commander, Pale Bay Leaf, ordered a retreat and decided to initiate Plan B. Molly contacted Eggman's ship and gave him her thanks for the rescue, and after learning the Chaos Emerald was on her planet, Eggman accepted her invitation to a meal of thanks since it seemed to them Eggman was going to join their fight.

Meanwhile, Shadow and Rouge had been sent to find the Chaos Emerald and Molly interrupted Shadow's thoughts with her thanks and telling him he was like Black Wind, a legendary hero on her planet that once protected their people from their enemies as he moved like the wind. Shadow became annoyed at being made out to be something he wasn't (a hero), leaving Molly discouraged. Later the trio interrupted an argument between the rest of the resistance and Eggman since they wouldn't be staying to help fight the Metarex like they thought. Molly then pulled Leon aside and asked him about the Chaos Emerald, which he claimed never to have heard of, but at Rouge's enquiry, remembered a meteor that looked like a white gemstone crashing on the planet that was now stored with the other minerals in a mining building far away. Before Molly could leave, Leon grabbed her and gave her a key to a cupboard which housed a disk with administration records to the mine, saying the old program could improve the system of their ship. Molly took the key with her, but was unaware it was actually a trap set up by Leon as part of his deal with the Metarex for an alliance.

Betrayed & Killed
Molly flew Shadow and Rouge in her fighter, explaining to Rouge the history of her planet along the way and how her people were becoming tired of losing and seeing their planet like this, wishing to have the power of the Metarex to protect her planet. Then they went on foot near a river, but in the water were giant fish creatures that leapt up and tried to attack the trio. Molly shot the first one, and the rest were taken care of by Shadow and Rouge. The two animals told her risking her life for others was a bad habit, but she insisted if she was killed someone would always be there to replace her before running off to the mine. Once inside, Molly found the box the Chaos Emerald was kept in and Shadow took it so Rouge could not snatch it, then Molly opened the cupboard the disk was supposedly kept in. What she found was a bomb that exploded seconds after the door's opening, but Shadow got the three of them to safety with his speed. As Molly realised that Leon had tried to kill her and wondered why, a Metarex fleet flew over the horizon. Rouge then realised what was going on; Leon wanted to get Shadow and herself away from Eggman to capture and deliver him to the Metarex and do away with Molly in the process. Molly then got into her fighter and flew off, despite Shadow and Rouge's warnings, determined to change the minds of her friends.

Molly found them trapped in the dirt in their fighters as a result of going up against Dr. Eggman's E-3000 and tried to reason with them, but they were so tired of living on a ruined planet and fighting a losing battle they did not listen, and only wished to live their lives instead of die in battle. Molly was reduced to tears by their words and Shadow landed on the wing of her plane, telling her to leave them and finish her life's mission before striking a Metarex ship. Molly thought of his words and, driven with grief, rushed at the Metarex mother ship with her guns blazing. The Metarex fleet then fired their weapons on Molly and Shadow rushed by her cockpit and she locked crying eyes with him before her fighter was hit and was was killed. Shadow was thrown to the ground by the force of the explosion and then removed his Inhibitor Rings before striking the mother ship himself, causing the destruction of the entire fleet. Later he made a grave marker out of debri and gave Rouge the Chaos Emerald to deliver to Dr. Eggman and left to fight the Metarex on his own.

Personality
Molly is a very determined young woman with strong beliefs that her planet can be glorious again and was always willing to risk her life for others, believing their would always be someone to replace her if she was killed. She is very trusting of her teammates and believed their devotion to be as strong as hers, and was reduced to tears when she learned the truth and made a reckless attempt to stop the Metarex, which resulted in her death. She also tended to talk too much, a fact she seemed to have accepted about herself.

Trivia
