I don't own the game but noticed in the preview images that it looked like Spike Spiegel was standing on the street in one. Anyone else notice this or am I just crazy?!

There are several easter egg characters from Cowboy Bebop in the game. I'm not familiar with that film, but I assume that Spike is one of these easter egg characters. You can find them from locations to where you don't have to go at that moment in the game, so just wandering around might be a good idea if you want to find them. All of them appear on planet Barracus.

Just came here to open a thread like this one lol. Yup, it's definitely a Cowboy Bebop reference.

I just met Ein and Ed, so I suppose Spike is possible.

Which is cool, because when I started playing that game, my first thought was "awesome, this is so like the bebop universe, let's pretend it is".

Yeah I've ran into Spike, Ed and Ein. Not sure how to find Jet or Faye though they are definitely in the game: https://www.youtube.com/watch?v=SY5yA1NI4q4
