Blue Lantern flew through the skies on seeing the signs of battle and sped up when he noticed the familiar yellow light. He saw Spiderman, Thor, Deadpool and Legacy with the Green Goblin and Electro taken down and narrowly avoided being hit by a lump of Clayface. As Spiderman managed to force Sinestro into hitting himself the lantern corps member burst onto the scene.

He created a large dense construct in front of him and sped towards the yellow lantern, hitting him in the back. 
"Hope burns bright villain! And there is nothing to fear!"
He fired another simple energy blast at the villain and flipped mid-air in order to dodge a construct blade as Sinestro turned. Ducking to avoid another, he held his ring aloft and pointed it at the villain.
"Fear is nothing when there is hope."
As the blue ring glowed, it drained energy from the yellow ring. As he acted, Sinestro's power gradually drained.
