Sentient Ultimate Echo Echo
|First Appearance||Map of Infinity|
The Sonic Disks are disks that can create sound waves. They are used by Ultimate Echo Echo to serve as his weapons against opponents.
Ultimate Echo Echo first used them in Map of Infinity to battle some Necrofriggian colonists. In Absolute Power: Part 2, Ultimate Echo Echo used the sonic disks to battle Ultimate Kevin. During the battle, it's revealed that the sonic disks can multiply and make a move called "Sonic Doom". Sentient Ultimate Echo Echo used the sonic disks to distract Gwen (in Anodite form) inside the Ultimatrix in The Ultimate Sacrifice.
In Greetings From Techadon, it's revealed that the Sonic Disks can continue flying and attacking when Ultimate Echo Echo turns back to normal.
