* Yes, you counted right. [[spoiler:Five Synchro Monsters at once.]]
* Yusei pulls a similarly awesome move, summoning 3 Synchro Monsters with 1 combo about 15 chapters earlier.
* Paradox gets one in the first chapter of Redeem Us. Yusei has already summoned Saviour Star Dragon, [[spoiler: on his first turn no less,]] a card which has spelled doom for countless opponents before; and not only does it do nothing to stop Paradox, [[spoiler:he bests it in one turn, with one straight-up attack]].
