Yeah, the fan art for LinkxViridi will be very strong, I guarantee it. Haha, yeah I loved that as well. Who wouldn't geek over Mega Man, really? Sakurai defiantly has quite a bit of respect for the Blue Bomber and it shows. Yeah, Lucina's was very touching and I did not expect that. They did her conversation justice I felt. What surprised me with Dark Pit's conversation was the subtle hint at towards a possible sequel and some insight into what happened after the ending of KI:U. For a fan of the game, that got me pretty excited needless to say. ^w^
Oh mine too! Nothing can't beat how amazing Robin's conversation was. I mean, out of all the conversations, his was the longest by far, along with a humorous cameo from Chrom. That's the glorious thing about KI:U's writing, it's incredibly witty, charming, full of personality, is very playful and it doesn't take itself too seriously for the most part, and it's dumbed down either. It's like watching an amazing saturday morning cartoon that be enjoyed by both children and adults alike equally.
I'm 100% sure that Mewtwo will also have his own guidance conversation like the rest of the characters, along with any other DLC characters. Sakurai 's attention to detail is staggering, therefore it's only naturally that we would add a Palutena's Guidance to Mewtwo, regardless of him being DLC or not.
