Spiderman black suit - Black Suit

Also, having copied all of Spider-Man's movements, the alien started sneaking back on to Peter's body after Peter had removed it and fallen asleep.

And most importantly, who made it? Unbeknownst to Spider-man, the alien was able to copy his abilities; the alien learned the chemical composition of Spider-Man's webbing, the frequency at which his spider-sense operates which allowed Venom to dampen Spider-Man's sixth sense , and could also copy his ability to stick to walls.

Also, there are white rectangles that appear on the back of the hands of the suit.

Upon discovering that the costume is actually an alien symbiote, Spider-Man rejects the creature by using high frequency sonics, and he wears a non-living version of the costume for a while.
