A brief personal opinion of the newcomers:
Inklings: Honestly, who didn't see them coming ever since Sm4sh? It was long overdue. It's like thinking there was not going to be a Frozen world in KH3, you would be lying to yourself if you said they wouldn't be in. Thus, I can't say I'm surprised. Their moveset looks pretty creative, though, so more than willing to try it out.
Daisy: I....I actually screamed of hype when I saw her. She's a clone, yeah, and it's not like having another Mario character is a surprise, but barely anyone thought she would make pass a possible alt for Peach. I'm simply excited for her and see what differences she has with Peach. Also condolences to Waluigi supporters.
Ridley: When his trailer started, my reaction was "Oh, Ridley, okay". Now, I'm not in the least against him, it's just that his more vocal and aggressive supporters and overabundance of memes back in the Sm4sh DLC days killed any hype I could have had but it didn't grow to the extent of making resent the character. So to me, he's fine, just that.
