Mine would be called "Voice of Legends". When used, the Guardian class would make a starfish-pose, very similar to the pose a Titan makes when using the defender shield super. During this, the "Voice of Legends" creates a medium-range explosion of light, while the "woah-ah-ahh!" part of the song Highlander-The One plays. As the Guardian stays locked in this starfish-pose with a beacon-like explosion radiating from his/her being, the radius of the blast increases in three bursts of light, finally reaching climax at the final "ahhhhhhh!~" of the verse, then the Guardian unlocks as the blast of light fades from the Guardian. Also the Guardian is invincible in the locked position of the super, much similar to the Titan Striker super, but since the latter blasts of the super are easier to avoid, I figured it'd be fair.
