I was having a conversation on Discord about late or recent characters for Smash, and i wanted to talk for a second about Crash.
When talking about Crash Bandicoot as a character that arrived too late or in time for Smash, we have to consider one thing: Skylanders Imaginators.
First, Activision had to contact Nintendo to get the permission for the compability with the DK and Bowser figures, so Nintendo had to know at least about general stuff of the game.
In addition, the Crash Bandicoot edition of the game, alongside the character and the remasters, were revealed at E3 of 2016, meaning that Imaginators started development around 2015.
It is possible that Nintendo knew to some extent about the Crash stuff, so Crash isn’t really a pick that arrived too late, all thanks to Skylanders Imaginators.
Take in mind that Crash in Skylanders wasn’t the same deal as Spyro in the first game of that franchise. Instead of showing him as another new character or just another random figure, he was promoted as a guest and a way to build hype for the remasters. It wasn’t something like “Crash Bandicoot is trapped in Skylanders alongside Spyro. Forget him now”, but instead something like “We are bringing back Crash, and we will put him in Skylanders to make the wait fast”.
