Legendary Ranger Modes

 * Legendary Ranger Modes for Legendary Battle:
 * Super Megaforce Red - Red Space Ranger
 * Super Megaforce Blue - N/A
 * Super Megaforce Yellow - N/A
 * Super Megaforce Green - N/A
 * Super Megaforce Pink - N/A
 * Super Megaforce Silver - Super Megaforce Gold, Silver Space Ranger
 * Troy and Orion's morph into the Red and Silver Space Rangers in this episode may provide a subtle reference to Power Rangers in Space final episode "Countdown to Destruction".
 * As of this episode, the following Legendary Ranger Modes have not occurred in the series at some point:
 * Troy is the only Super Mega Ranger to not transform into a different-colored Ranger.
 * Orion, on his own, has never transformed into the Quantum Ranger, Lunar Wolf Ranger, Green Samurai Ranger, Omega Ranger, Solaris Knight, Mercury Overdrive Ranger and RPM Gold & RPM Silver on their own, nor Robo Knight.
 * None of the Super Mega Rangers have transformed into the Black, Blue, and Pink Space Rangers, any of the Lightspeed Rangers, the Time Force Rangers with the exception of Pink, and the Overdrive Rangers with the exception of Red.
 * There has been no single colored team Legendary Ranger Modes besides Red and Black.
 * Nobody transformed into Blue Senturion, Magna Defender, Shadow Ranger, Kat Ranger, White Mystic Ranger, Sentinel Knight, Black Lion Warrior, Green Chameleon Warrior, or Red Samurai Ranger ♀.

Errors

 * During the beginning of the episode, when Troy gets up, a crew member is in the back on the phone.
 * When Gosei says that the zords were lost, he referred to the Sky Ship zords. However the rangers never take note of the Gosei Mechazords, which were never destroyed during the battle with Vrak's commanders. Why they didn't resort to those is unknown, but possibly because of power reasons.
 * When Noah, Gia, Jake, and Emma use the Super Mega Cannon, we can see the Keys of the Shadow Ranger, Female Red Samurai Ranger, Sentinel Knight, and White Mystic Ranger. This is due to using Gokaiger footage, as the Gokaigers used the DekaMaster, Princess Shinken Red, Great Sword Man Zubaan, and MagiMother Keys for the GokaiGalleon Buster.
 * RyuuRanger can be seen fighting alongside the Jungle Fury Red Ranger and HououRanger can be seen in the background.
 * However, they could actually be the original Red and Pink Rangers of the Legendary Squadron.
 * FivePink is seen before the charge, but again it could be the original Pink Ranger of the Supersonic Rangers.
 * ChangeGriffon and ChangeMermaid are seen beside the Mighty Morphin Power Rangers during the battle but, like the other two, they could be the originals Black and White Rangers of the Dragon Powers Rangers.
 * The White Mighty Morphin, Zeo Ranger V, and the Black Dino Thunder Ranger are briefly glimpsed in long shots of Sentai footage. Because these rangers are all Tommy's Ranger forms, they cannot be on the battlefield at the same time as the Green Mighty Morphin Ranger. It is most likely that these instances are not intended to be appearances.
 * The Mighty Morphin Yellow Ranger has a skirt in original footage when she didn't originally (it's likely the producers mixed up the original suit with the one worn by Gia Moran/Luka Millfy when they morphed into the Mighty Morphin Yellow Ranger/TigerRanger).
 * Titanium Ranger's mouthpiece is visible, when it should be behind his visor.
 * When the Rangers finish off the remaining XBorgs and Bruisers with the Megaforce Blaster and Super Spear Blaster (in Orion's case) respectively, the beam of the Super Spear Blaster instead hit the XBorgs and Bruisers without waiting for the Dynamic Victory Charge blast of the Megaforce Blaster.
 * During the aftermath of the battle, the silver stripe on the Green Ranger's helmet can be briefly seen when Tommy walks up to the Rangers.
 * The Red Turbo Ranger does not appear in the wide shot of all the Ranger teams on the cliff, but does appear alongside his team in close-ups.
 * Likewise, Tommy and Antonio do not appear in their respective team's shot, but do appear in the wide shot on the cliff.
 * Also many rangers who later appear in the battle, including the Thunder Rangers, the Samurai Ranger, Tyzonn, Merrick, Sam, and Gem and Gemma do not appear in either the cliff shot or their team's shots.
