Given the cue when Blaze shot him in the back, Izaroth promptly vanished, and appeared above Trunks before crashing both fists down on the half-saiyan's head. He wasn't stopping there though; holding both hands out diagonally upward behind him, he then fired two Ki-Blasts powerful enough to blast him in the direction he was aiming, yet short enough of range that it wouldn't cause any damage to the surroundings. The whole point of this was so Izaroth could promptly strike Trunks in the back with his feet while he was still reeling, and knock him to the ground.

"Remind me to teach you the vanish technique at some point." Izaroth said, looking at Blaze as he spoke, before turning his gaze to Trunks.
