Delta Accel Synchro Summon (デルタ・アクセル・シンクロ) is a form of Synchro Summoning in the anime, in which there is one Tuner Synchro Monster and two non-Tuner Synchro Monsters used in the Synchro Summon. The only known Delta Accel Synchro Monsters are "T.G. Halberd Cannon" and "Cosmic Blazar Dragon". "T.G. Halberd Cannon" was used by Antinomy, when performing Top Clear Mind in episode 144. It has also been shown that performing Delta Accel successfully can accelerate the lifespan of a nearby star, causing the giant star near Antinomy to explode and collapse into a black hole. According to Antinomy, this is a Synchro surpassing Accel Synchro.
