Ok look. I doubt in terms of timeline, Wind Waker Link and Phantom Hourglass Link are related to Minish Cap Link but in terms of Look-Alike, I bet if Minish Cap wasn't 2D and was 3D, he'd be another Tink.
Toon Link is just basically all Links that look cartoonish with big eyes and such. That means all these links I posted are Toon Links, including TMC. TMC has the same style as FS and FSA Links, and they are all cartoonish. So yes, TMC Link is a Toon Link.
It's the BELT that really makes you think. They have identical belts.
Which makes me wonder, perhaps there were TWO hero's outfits handed down, one in each timeline? The child bearing OoT Link, and the Adult path bearing Minish Cap Link?
The only difference between the Links that I see in Smitie's evidence is the sword. But they were using different swords anyways. Also, if you stare at it long enough, WW Link's tunic seems to be a deeper green than MC Link's. MC's sort of looks mint.
