Ice Machine

Sentient robot rapper who has a beef with other robot rapper M.C. Chuck Fifteen. From Instead of rap music, it's called scrap music- get it?! Hanh? Hanh?! He's not seen, his song plays in the background.

From comic book Top 10 # 6 (February 2000, America's Best Comics), set in a city where everyone, EVERYONE is a superhero, and robots are an underclass and derisively referred to as "clickers."

Lyrics:

Yo Listen up clickers,
This is Ice Machine,
With a message here for M.C. Chuck Fifteen

Ohms, you ain't so drastic!
Y'ain't metal, yer plastic!
I'm clanging your glitch,
And she says I'm fantastic!

And as for your mom
the chute that yer from
I had her on the blocks,
and she thinks I'm the bomb!
