2019: Apocalypse

2019: Apocalypse (2019：アポカリプス) is the forty-ninth and final episode of Kamen Rider Zi-O. It is the third and final part of the Kamen Rider Decade tribute arc. It features the full debut of Kamen Rider Tsukuyomi after her brief appearance towards the end of the previous episode, the revivals of Heure and Ora (the two of them having died in episodes 45 and 46 respectively), Sougo's transformation into Ohma Zi-O and Swartz's death.

Synopsis
Bear witness to the birth of Kamen Rider Tsukuyomi! However, this miraculous power will be used in an unexpected way! Did Tsukasa and Sougo's plan ultimately fail?! As the end of the world is approaching, much to the contrary of what the situation might show, Sougo's heart remains terrifyingly calm! Because hidden deep within him lies his secret resolution...

Plot
"All thanks to Sougo Tokiwa's efforts, Tsukuyomi has become a Kamen Rider. However, her choice to defect is unforeseen. This is the very last page...until the end of the world..."

- Black Woz

"An ordinary high schooler, Sougo Tokiwa awaits a future where he becomes the demonic king of time, Ohma Zi-O. Or will he? We don't know yet. For on this day forward... A new history, different from this book, will need to be scribed."

Errors

 * In the credits, Masahiro Inoue and Kimito Totani do not have the names, Kamen Rider Decade and Kamen Rider Diend next to their characters names even though they were transformed in this episode.
 * When Decade inserted the Final AttackRide Card to Neo Decadriver, the text displays "AttackRide: Slash" on the buckle, while it announces "Final AttackRide: De-De-De-Decade!".
 * In the GrandZi-O transformation sequence, the CGI pedastals are placed perspectively wrong along with Sougo's green screen lines weren't cleaned well.
 * The GrandZi-O Ridewatch was reformed even though the Decade Ridewatch isn't in Sougo's possession anymore and was returned to Tsukasa in episode 47.
 * Although, GrandZi-O did fight simultaneously with Decade against Another Zi-O II in the same episode as well. This may indicate that the GrandZi-O Watch is usable as long as the original Ridewatch or power stays intact.
 * In addition to that, Decade Ridewatch is also present among the watches absorbed by Ohma Zi-O.
 * Evol Cobra Form (Phase 1) can be seen generating black holes in his attacks, something that Evolto can only do in his Black Hole Form (Phase 4: Perfection) and monster form.
