Guardians of Obsolete Formats

The Guardians of Obsolete Formats are characters that appear in the episode "The Last Laserdisc Player". They were activiated once Mordecai, Rigby, Muscle Man, and High Five Ghost put the correct items in the proper spots. The Guardians of Obsolete Formats were meant to serve the holders of the laserdisc and protect them from any harm. The Guardians soon found themselves fighting the Ancient Order of the VHS and appeared to be winning the fight. However, the Guardians ended up fighting the VC-Arbitrator and started to lose the battle. Fortunately, the Librarian transformed into the Laserdisc Guardian and defeated all of the members of the Order and the VHS Robot as well. The Guardians then watched the movie with Mordecai and the others at the end.

Description
The four different members of the Guardians of the Obsolete Formats include Betamax (whose head resembles a projector), 8-track (whose head is round with two small knobs on it), Floppy Disk (whose head is flat and in the shape of a rectangle), and Reel-to-Reel (whose head is a reel-to-reel player). They all have muscular bodies and are able to use different kinds of superpowers.

Trivia

 * Out of the group, only 8-track was killed.
 * Like "The Guardians of Eternal Youth" they too have lost a member.
 * In "Format Wars II", the only guardian who still lives at the end is Reel-to-reel since Betamax and Floppy Disc died during the battle.
