Characters on Heroes sometimes reference the song "Mr. Roboto" by the Styx.
At the specials for hire bar, Knox tells Hiro and Ando to look tough. Ando puffs out his chest and assumes a stiff posture, but Hiro says, "He said look tough, not like Mr. Roboto." Ando explains that that's his tough guy walk.
- The song "Mr. Roboto" was performed by the Styx on their 1983 album Kilroy Was Here.
- The Japanese lyrics of the chorus repeat "どうもありがとうミスターロボット (Dōmo arigatō misutā Robotto)" which translates to "Thank you very much, Mr. Roboto."
