Just because Bunnie and Sally provide Tails with stories, doesn't automatically mean that Mina couldn't. While it does serve as bonding time for him and the girls, I'm sure both of them could use someone to step in every now and then when they have to prepare or rest up for a mission late at night. Plus, while the Freedom Fighters are undergoing missions, Mina could easily look after Tails OUTSIDE from bedtime while they're gone if she isn't occasionally chosen to go herself. This would easily give her an understanding of aspects of Tails' personality that might often go overlooked by some of the other characters, who're usually too busy to deal with him--especially during a time where he's growing up. If Tails is eventually developed to become gradually more rebellious against the other characters like he was originally intended, Mina's understanding of him would might be crucial in helping the others deal with him, especially Sonic if or when the conflict arises.
Well it does make sense that someone would need to look after Tails if all the Freedom Fighters were away at night, but such details were ignored back in the original SatAM in favor of showing our heros on a mission.
Of course Tails being told a story a day before a mission or right before one, and using the stories to perhaps apply them to a plot and teach a lesson to him could aid in his development and would be crucial in expanding his character. AND in SatAM the focus wasn't really on Tails. But times are changing. So such details surrounding Tails could be expanded on ocassion if he gets any attention.
To be honest Tails will have to show that he doesn't want to be treated like a little kid before, thus the full emotional impact of Tails's resistance can only be achieved by him being disobedient towards Aunt Sally herself. Mina on the other hand is just some standard babysitter who many of us have never seen interact with Tails before. And since this role amounts to nothing more than a glorified babysitter, why not just use Rosie the Nanny from "Blast to the Past"? Sure she never appeared in the show after that, but at least we'll get a SatAM-continuity bonus by seeing her once more before she disappears into the background after fulfilling her role in Tails's character arc.
1. Because Mina's role doesn't have to be anything other then a babysitter.
2. Because Mina's far more popular today than Rosie ever was.
3. Introducing Mina could provide an interesting story.
Maybe Mina wouldn't read to Tails forever, but she could for awhile, and storytime might just be an opening wedge for her to interact and become closer to more characters. Even if she stopped reading to him, and wasn't his babysitter anymore, she'd still be his friend anyway. This is just a means for them to develop as more as friends.
The thing is that Tails shouldn't be having to go through storytime anymore, he needs to grow out of it. For the sake of keeping the cast of Freedom Fighters at a manageable level, either Sally or Bunnie can be the ones to learn about Tails growing up the hard way.
And they would. But Tails can still develop with Mina's help. Adding a mongoose on occassion is NOT going kill SatAM.
Also, Tails' could use her as someone to convince Sonic and Sally to allow him on dangerous missions if they both in one story agree not to let him go. Mina babysitting Tails could also give leway for him to interact and take part in activities with other characters like Amy, who may drag both Mina AND Tails into her misadventures for Sonic's affections.
I'm not sure how the babysitter is supposed to be the one who tries to convince the guardians to let their kid go with them.
1. Maybe if the babysitter actually went on a few missions here and there. Not only that but and Mina could uinintentionally wind up in misadventures, that expand on the morals presented in their storybooks. Teaching valuable lessons to Tails while giving him the expirience to make Mina see him as fit to be a Freedom Fighter.
2. I think that if Mina were a mole, she'd have to be in on the Freedom Fighting already. So she'd probably be an occassional member of the team regardless.
If you think this would be a good chance for Tails to interact with Amy, then why not just make things simple and make Amy the babysitter who abandons her responsibilities in favor of her schemes for Sonic's affections?
Amy is only 2 years older then Tails. She's his peer. If anything, Mina would be watching over both of them.
I bet that Tails and Amy could become very great pals under this situation; both see Sonic as their hero (they can even bicker over who is Sonic's greatest fan) and both would have a desire to show their worth as Freedom Fighters. Eventually they will both end up proving themselves in combat (after some mishaps obviously) and become full-fledged Freedom Fighters. With such a dymanic, we wouldn't need a glorified middlewoman like Mina involved.
And Mina, their caretaker can't be in on it in similar fashions as mentioned above? Logically speaking ,the first person to know they're gone is likely to be their caretaker, and they'd be in on the mission too anyways. She can also serve to teach easily impressionable children lessons while trying to take care of them on their misadventures? Similar to Julayla and Sally? Again as Shorty mentioned, Mina can also provide someone in AMY'S court. Tails thinks romance is gross, and everyone else would put Sally first, or would simply fail to take her seriously. That doesn't even deal with the ways Mina can support the other characters. Amy is far too invested in things like clothes and shopping to truly understand the value of things deep down. A lesson Mina should at least offer to help Bunnie come to grips with it. Amy is very Sonic centered, and wouldn't really care about the other characters that much. Any characters who do wind up in Amy circle get suckered into her schemes. She doesn't really have many dynamics to offer compared to Mina. Speaking of Amy she'd need a new outfit. There's no way she'd get around with that "trendy" outfit in SatAM.
SatAM is SatAM, it's not SegaSonic, it's not Archie.
Again, so what? Adding Mina does not necessarily mean the show is transforming SatAM to Archie. It also pretty obvious that Mina would have to be modified somewhat to fit SatAM, and would play a different role considering the difference in status quo.
As for Amy fans being upset with Sally, well I don't know what to tell you except too bad.
Which is what this is all about, another Sonsal shipper...If you want to say your peice about Mina please at least discuss this in terms of storytelling.
SatAM is its own thing and should be treated as such. Yes it has Sonic, Tails and Robotnik but that doesn't mean it has to include Amy because the modern Sonic fans don't like Sally. Sally will upstage Amy even if she is included because let's face it, Sonic is interested in Sally while in no continuity does Sonic consider Amy little more than an annoyance. Let's not forget that as she is, she'd be a useless Freedom Fighter. What are you going to do? Turn her into a warrior? Well that would annoy the SegaSonic fans because she's not a warrior in the games. She has a ridiculously large hammer yes, but she rarely uses it effectively and it wouldn't fit in with the SatAM setting. Replace it with a sword or something? Good luck in using that effectively against SWAT Bots.
If you want to keep the SatAM feel you're not going to please the SegaSonic fans no matter what you do, so the "Sally upstaging Amy" argument is moot. As for Archie comic characters like Mina, as I said before... no point.
Granted you can't please them all, but you can please a lot more of them by at least adding Amy and Knuckles and increasing Tails' role to the series so it's not moot. And you're right you do have... no point. I don't want Mina simply because I don't like the fact she came from the comic. Sorry but that arguement's pretty weak and lies only on your own personal biases to the comic. Mina could be changed to fit in SatAM, and her dynamics with the characters don't demand SatAM to change.
