April Fools trailers
Why is it that only Mr. Incredible's trailer gets to be shown there? Imo, either all April Fools trailers should be shown there, or none of them. I'm more inclined towards none of them, because we already have a page for that. Maybe just make a short summary about these trailers, and use the Template:Main on top of the section?
Well, there's one thing to consider there, and it's that the page is showing every April Fools' Day trailer here, those being Mr. Incredible and Sandbag (if you can call it one). As for the rest: 2018's Flash Minus video is more like a showcase, 2017's stage fighting video is a gameplay match with only one trailer-like element at the very beginning, and even 2019's Trophy War teaser doesn't count because it's for a mobile game spin-off and not actually SSF2.
And I get what you're saying about the Mr. Incredible trailer already having a home on the wiki, but ultimately, a trailer's a trailer regardless of what gets revealed, and I personally think that's enough of a reason to keep it listed.
