I've been playing Xenoblade 3 Future Redeemed and man I still can't get over how dirty Shulk was done in smash
He acts nothing like him, he doesn't sound like him (which is weird considering he has the same actor he does in XB), He looks nothing like him, The moveset is mostly fine, but even then, the Monado Arts are mostly unique for Smash. Not to mention the final smash Spoiler for XC1 They added Mecha Fiora which breaks the original reference because you can only have 3 members in your party Just all around it is a portrayal that has aged poorly.
honestly, Mega Man, Sonic and Shulk are the 3 veterans I would personally rework, Sonic is obvious, Shulk I just mentioned and Mega Man is so soulless and Lifeless when that is actually the exact opposite of how he is portrayed in the Mega Man games.
