Tingle is easily my most preferred Zelda newcomer. After that, it's Pig Ganon and Impa. I mostly shrug at the others, though I wonder how fun Toon Zelda and Toon Sheik as a team would've been.
I got a lot of my wanted newcomers overall. There's still many left outside of Brian; Rabbids, Dixie Kong(I'm now preferring her as a tag team idea these days. I'd love to have fun via DKC's concept), Waluigi, Toad, Scorpion, Fulgore, Shadow, Isaac, the three I mentioned up above, Geno, Steve, Master Chief, Agumon, Nightmare(Soul Calibur), Bandanna Waddle Dee, Slime. I can't think of any more off the top of my head.
