Oh wow, I remembered Cowboy Bebop aired on Adult Swim back in early 2000s, also they ran frequently through the 2000s.Yeah, that's pretty sad. For those who are wanting Cowboy Bebop, or Trigun coming to Toonami Rewind, you're going to be heavily disappointed.
Cowboy Bebop on Toonami Rewind? Extremely unlikely for sure. Toonami Rewind was like more of Cartoon Network's Toonami back in 90s and 00s.
