Danny is the lead singer of the band Ninja Sex Party.
He has a "sidekick" named Brian, or Ninja Brian, who is a pianist and keyboardist.
Danny made his first appearance on the channel in Ode to Jon, followed by his Mike Tyson's Punch-Out!! Despite being recorded months prior, the first episode of Steam Train, Who's Calling? Due to the massive amount of changes on the Game Grumps channel announced in the matter of a couple of hours, including Jon's departure and the introduction of Danny, Ross, and Steam Train, Danny was not initially happily welcomed to the Game Grumps channel by fans, due to a combination of having become accustomed to Jon and Danny's openness about the fact he was not a deeply-involved gamer as Arin and Jon had been.
Early videos of Game Grumps with Dan and Steam Train received more dislikes than most previous videos on the channel, and there was much controversy among the You Tube comments and the subreddit.
In the Spring of 2003 the band broadened to include multi-talented Alex Yaker and drummer Ian Creech.
Their website is now defunct, though their Myspace page remains.
The series was not received well, and was dropped after the first 12-episode season.They have six albums out, NSFW, Strawberries and Cream, Attitude City, Cool Patrol, and Under the Covers Vol 1 2, an album of covers from the 1970s and '80s.NSP started out at a UCB as a musical guest at Danny's storytelling teacher's show, "Strip Stories".Danny mentioned that the Mondo Media staff experience was welcoming, although he was not confident that the way his character was written would appeal to audiences.Danny also created, wrote, and provided voice acting for the studio's short-lived animated comedy miniseries DJs in PJs.
