>>471592>I want them to lose gracefully
And therein lies the problem. Pretty much every single villain so far in G4 has fallen not in spite of, but because of themselves to some extent. To me it seems to simply be the way the show is written by the crew. Because of that I find it unlikely any villain, even if brought back from the past, would lose gracefully. Well, I guess that depends on what exactly you mean by that, but still. For better villains and whatnot I'd direct you to the magical world of fanfiction~
For facing him alone, do you mean that she should defeat him alone, as well? If not, I could see the M6 falling behind one by one, tackling whatever problem they are facing, urging Twi to move along because they are in a hurry. Then they could catch up just when Twi is about to be defeated or whatever if you don't necessarily have to have Twi win alone. You'd still be able to do a showdown of some sort. Yes, I love that particular type of thing, whether the rest catch up at the end or not. Self-sacrifice and the rest having to move on despite that. Strong stuff, though not necessarily right for this show the way I'm thinking.

Because come on, Friendship is Magic~
If you wanted Twi to defeat him alone, as well, yeah. It kinda does go against the dynamic and the whole Friendship is Magic thing, though Twi being a princess would make it more likely, as does them losing the Elements. She is the most special one even moreso than she was before. Still wouldn't be holding out hope for that, though, even if it could make for an interesting story.
As for the analyses on Tirek and pals, I guess the problem there is that a smart villain is just a hard thing to deal with, especially in a format such as this. There's only so much you can do in twenty or fourty minutes, so introducing a villain, making it clear they are competent (and still allow the heroes to be able to find a way to defeat him while maintaining the illusion of the villain being powerful) and then having the heroes come up with that way of defeating them and doing the deed, as well as the post-combat happytimes… It would need way longer than a few episodes in my mind to do a story like that justice. Don't get me wrong, I'd love to see that myself and lament the villains being stupid in this show, but I don't think it is something I should expect from this show. One can always dream, though…
