Audio file

EchΘ Θnslaught is a song performed by Free Association. It is played during the Parallel Canon boss fight in Side Order.


EchΘ Θnslaught is a fast-paced energetic electronic song, composed of synths, electronic drums, and various short vocal samples. Once the player completes the boss fight, the drums will drop and synths will resolve, and the song will end.


  • The section beginning roughly 48 seconds bears a melodic similarity to the bridge of Inkoming!; a song often treated as the main theme of Splatoon 2. This could possibly be another way of implying a connection between Parallel Canon and Agent 4.
  • Portions of EchΘ Θnslaught are strikingly similar to the songs 魔​法​渦​状​Lovely You! and Mimicloq by the producer Nanoray.[1] Nanoray themself has acknowledged the similarity.[2][3]


The name of the song correlates to the name of the boss: a canon is a musical term that defines a melody being played, followed with imitations of the same melody, with a delay for each iteration, giving an echoing and overlapping effect. Additionally, the use of Θ (theta) to replace the visually-similar "o"s in the song title may be a reference to it being the eighth letter of the Greek alphabet, tying into the octopus theming of Side Order.
