Mina Mongoose

Mina first appeared after Eggman’s forces had captured her mother, and Mina wanted to go save her before she was roboticized. Soon she found herself under attack from Eggman's men, and was saved by Sonic the Hedgehog. Sonic told Mina it was probably too late and that she would probably risk the same fate. This response upset Mina because she didn't think Sonic understood how she felt, but Sonic explained that his own parents had been roboticized too. Having someone who understood how she felt seemed to calm her down for that moment and Mina would go with Sonic and the other Freedom Fighters to Knothole. After this, she had started having feelings for Sonic. When she went to school, Sonic gladly let her feel at home, but Bunnie would not act kind toward her.

Once Mina arrived at Knothole, she would mourn over the roboticization of her mother and dealt with moments where she wished she would be roboticized so that she be with her mother. Mina managed to head out of such times, by getting a job with Rosie babysitting orphans who had lost their parents like she did. Her sentiments towards Sonic, also changed during her stay in Knothole. While he explained that he understood the nature of Mina's loss, Sonic still seemed to her rather distant. It was only until she walked in on an intimate moment between Sonic and his parents, did she respect Sonic as a hero who had a soft side.

Regardless, Mina would not have an encounter Sonic would recognize until much later. At this point, Mina's depression over the loss of her family led a desire to confront Robotnik herself. For Sonic, he was heading to Robotropolis to restore free will to his uncle using the sword of Acorns he had stolen from the kingdom. After a brief argument over the motives one another had for going to robotropolis, the two would deal with an ambush that would result in the loss of the sword of Acorns.

After the incident, Mina would find herself trying to cover up Sonic's theft since she could finally bring herself to respect Sonic as a hero. This however didn't go on long as the Acorn Kingdom's Secret Service began to suspect Sonic of stealing it. By telling Mina they would avoid persecuting Sonic if she told them what happened, they received the confession from her that they desired and went forward confronting Sonic whose knighthood would be removed due to this incident. She would also begin life as a school girl, and would be Sonic and Bunnie's classmate. Bunnie wouldn't take kindly to Mina due to noticing that she could very well end up as competition for Sally over Sonic's affections, so Sonic would be her only close friend.

Eventually, the time would come for Mina to go with Sonic as his friend and as a comrade. The mission was at Robotropolis, and originally the idea was to rescue Nate. However, with the Sword of Acorns found wielded by Sally, the free will of the Robians (roboticized Mobians) was restored. Mina on the other hand would undergo a scouting mission for Nate. Though the mission was ultimately a failure, Mina received her first taste of being a team player, and would also aid the Freedom Fighters in safely helping the Robians out of the city. When everyone had reached Knothole, there were many reunions, including that of Mina's reunion with her mother, Isabella.

Despite being officially friends, Mina did make attempts to get Sonic's attention. At first it started with a "thank you" kiss. Then, when it provided a reaction that was described as "more surprised than pleased" she'd move to asking for advice about her next move. She decided based on the advice provided to continue her attempts through other methods such as dressing up and trying to become a Freedom Fighter like Sonic. During her time as an official Freedom Fighter, Mina had been trained in piloting, swordsplay, physical endurance and computer programming. However when a giant robot of Eggman's attacked Knothole, Mina had no idea how to apply her trained naturally cultivated strengths to impress Sonic in such a dangerous situation.

Mina would settle on responding to a group of children that the bot endangered. She tried to get the kids out of harm's way, but was overwhelmed by panic. Luckily, when the robot was about to step on Mina, it stopped mid step thanks to Rotor reprogramming it. Mina realized after the ordeal that she at that time was trying to apply skills to impress and be near Sonic, not to save the world or to defend anyone (herself included). Realizing this job was too dangerous to apply her strengths to get Sonic's attention, Mina quit and began to focus more on a singing career (which Sonic encouraged her into after hearing her sing.)

She has also been an occasional battlefield heroine, even after her stint as an official Freedom Fighter was over. Mina appeared a few times during the worldwide assault against the Xorda. Mina is no longer trying to apply her skills to impress Sonic when working with the Freedom Fighters. Instead, she's worked more to apply her talents to compliment the team's efforts, and without previous obstacle her performance on the battlefield has been more successful.

Since Mina was recognized by Knothole as a talented singer, Sonic and Mina had shared a concert together that gathered a lot of success. Her solo concerts have also been very successful, and have been directed at lifting the spirits of the troops throughout their war with Robotnik. The band she's been known to work frequently with in Sonic's absence are known as the "Knothole Knuts", although it has not been clarified if they are Mina's band. Her singing career has also allowed her to establish a bond with the masses, something she hadn't attained when she first arrived at Knothole when Sonic was her only friend. When Mina is set on continuing the concert, even though her life is in danger because she wants her fans to be happy.

Mina's career as a musician has also helped her establish a stronger bond with the people. So like her comrades, there is arguably a much more genuine desire to fight for the people than there was before. As a result of her hazardous occupation, she is often accompanied by bodyguards, an assignment that has fallen on Knuckles the Echidna and the Chaotix several times. She went on a world tour to rally support for the war, and was thus not present when Knothole was destroyed. However, she came to New Mobotropolis shortly afterwards, only to fall victim to the predations of Mammoth Mogul. The megalomaniac had met Mina some time before, having been the one to give her her enhanced speed so that she could save her mother. Her memory erased and a post-hypnotic trigger planted in her mind, Mina forgot all about Mogul until he forcibly recruited her as a member of the new Fearsome Foursome.
