I am searching for an animation with two partners. They travel around the world, and they have robots suits. I remember the suits have some neuronal connections with the pilots. The main character has a red robot suit with a spear or some kind of weapon that can penetrate anything.
It's an old show. I know that I saw it when I was a really young man (around 2001-2002).
I've seen a lot of anime with mecha, and yet I didn't find this animation. It's not any of the Gundam series. As noted in my response to two of the answers below, it's also not Neon Genesis Evangelion or Tekkaman.
What I remember: they were riding a car with robots, the main character was sick, his partner was about 50-55 years old, the robot was red, and I remember very well only one phase, an enemy it is not worth remembering if a sword was a spear, but I know it was a symbiosis between the two, the robots were not as big as evangelion and did not fight in space as some of the gundam, I know it has a sharp shape, and it's like if you remember the latest versions of blue genders robots.
