This pic also borrows from Steve's trailer, specifically with Crash in the place of Mario. I ditched Smash-Stars as a whole, but I do like how this pic turned out. The background behind Astro is meant to resemble the PS2 intro. The stuff written below is the description I made for it back when I posted it.

  The next fighter on Smash-Stars' Fighter Pass is the PS5's mascot, Astro. For those who don't know, Astro's Playroom is game that comes with the PS5, and is basically a trip down Playstation memory lane. On top of collecting Playstation products through the game, setting them down in a sort of museum room, you see a bunch of robots like Astro acting out or referencing so many Playstation games, there's a whole list of them. A few favorites I've learned about(I don't have a PS5)are...

Crash Bandicoot-A Robot in a Crash Bandicoot mask doing his victory dance.

Parappa the Rapper/Um Jammer Lammy-Cardboard cutouts of Parappa and Lammy bots playing music.

The Last of Us-Joel and Ellie robots hiding from a Clicker bot(A robot with flowers over his face).

Until Dawn-Some robots on an iceberg resembling the Until Dawn cast, complete with a butterfly.

Castlevania: Symphony of the Night-An Alucard bot sleeping in a coffin.

Detroit: Become Human-Some bots standing on displays like Androids, one deviant among them.

  Of course, Astro here comes with a new stage, aptly named Astro's Playroom. This stage is a shifting one(Like Castle Seige), going through different environments displayed in Astro's game. With some of the references from said game visible in the background. That being said, Collision Mode has a unique effect on this stage, as it goes through areas of different games not on the Playstation, but rather...Nintendo Land! Of course, Collision Mode also gives us more references to see, some of which you can also see on Battlefield or Omega Modes, with certain Fighters making those references more likely to pop up. Such include...
