So it was back in 1998 I saw an anime for about 5 minutes before I had to leave with my parents to go to the grocery store. It was on the Sundance channel which used to play amazing stuff way back when.
The anime was subtitled. I remember there were these black kids fighting this monster blob in New York City, the kids had machine guns and a few of them got killed by this blob with tentacles. The anime simultaneously showed a headquarters in Tokyo with a tall guy in a suit who looked like the main character of cowboy bebop. He had a robot with a triangular head who teleported to New York City. The robot was tall. It's body was either gray or white and its inverted triangular head I wanna say was purple? It then saw the blob and said "I've traveled 2000 years from the star Vega for this moment" and as it said that, it made the sky black and this green laser rain came down on the blob, which induced injury, but angered it and made it transform into something...
That's all I remember from it. I've been looking for years and have asked anime fans about this subject and they have no answer. Hope someone can help!
