A Limit Over Accel Synchro Monster (リミットオーバーアクセルシンクロ Rimittoōbāakuserushinkuro) is a sub-type of Accel Synchro Monster, which is itself an anime-only subtype of Synchro Monster. All Limit Over Accel Synchro Monsters require at least three Synchro Monsters as Synchro Material (one Tuner Synchro Monster and the rest non-Tuner Synchro Monsters) for its Limit Over Accel Synchro Summon, and can only be Summoned when the player is in a state of Over Top Clear Mind. The only known Limit Over Accel Synchro Monster is "Shooting Quasar Dragon".
