What is this I don't even
Link and Toon Link are not the same character, not even close.
"Turning him into a cartoon somehow"? Are you trying to argue that Link actually, canonically became a cartoon? That's what it sounds like. It's just a different art style.
Also... Link putting the Master Sword back didn't affect the timeline. OoT Link was erased from the adult timeline when Zelda sent him back. The time in which he reappeared became the child timeline. The Links who came later on were his descendants or spiritual successors. Also, the adult timeline doesn't have a Four Swords game. The Unified and Child timelines do.
Why is this even being argued over in the first place? What relevance can this possibly have here? Link and Toon Link aren't even alt costumes. They have nothing to do with this.
I say that cause Metal Sonic is yes in fact a different character, a different matter, but its like Link and Toon Link.

What on earth are you even trying to argue here? Do you even know? You're going back and forth between saying Sonic and Metal Sonic are and aren't the same and you're trying to compare it to Link and Toon Link. Your arguments are incoherent. Start making sense!
To actually try to have this post be on topic - I really want to see an Ice Climbers alt with their hoods down. This was mentioned much earlier in the thread, and I think it's one of the few alts that could possibly make sense for them.
EDIT: Well, I got severely ninja'd by far too many people.
DUDE, quit posting that page from Hyrule Historia if you haven't read Hyrule Historia. The very same book that comes from explains that almost every Link is a different one, with the games taking place hundreds of years apart.
