New Powers

As part of the Super Mega Rangers new power set, Gosei has given them the ability to not only transform into Historic Rangers but to actually unlock "new powers" never before seen on Earth. These powers represent teams that have never set foot in contemporary Earth. Whether they are aliens, like the Aquitian Rangers or Trey of Triforia, dimension-hoppers like the RPM Rangers, or from the future like the S.P.D. Rangers or the Time Force Rangers is unclear. However, unlike those Rangers, that their powers have never been utilized where the Morphing Grid is located currently on Earth is certain.

Legendary Squadron Mode
The first new Ranger powers that the Rangers unlocked seemed similar in appearance to the White Ranger of the Mighty Morphin Power Rangers, albeit with white details instead of gold or black. They also had a theme strangely similar to the Thunderzords which consisted of legendary animals. They had the ability to channel energy (similar to 'chi' energy) and blast it at the opponent. The Super Mega Rangers, except for Troy, unlocked these in their battle with Cybax's XBorgs. Later, they used it as a team with Orion partnering up with them to become the thematically similar Mighty Morphin White Ranger. Their group attack is the "Legendary Strike".

Green Ranger
This Ranger had a motif of a majestic Lion as seen in oriental art. Jake was able to unlock this.

Blue Ranger
This Ranger had a motif of a Pegasus. Noah was able to unlock this.

Yellow Ranger
This Ranger had a motif of a Qilin, a chimera-like creature. Gia was able to unlock this. The Ranger Key shows the original powers did not have a skirt.

Pink Ranger
This Ranger had a motif of the Fenghuang, a mythical bird from Chinese mythology. Emma was able to unlock this.

Red Ranger
This Ranger had a motif of the serpentine Chinese dragon. It is unclear if it came unlocked with the other powers or if Troy had unlocked it before the battle with Matacore. Troy considers this one of his most powerful close combat Legendary Modes.

Lightning Mode
The second power set the Rangers were shown using were featured during the battle with Matacore's XBorgs. These Rangers seem to be highly adept at martial arts.

Yellow Ranger
Gia chose this Ranger as one of her most powerful Legendary Modes to sense coming attacks. She called it Legendary Ranger Blitz.

Blue Ranger
Used by Noah during the final battle with Levira.

Prism Mode
The third power set the Rangers were shown using were featured during the battle with Matacore's XBorgs. These Rangers seem to use hard light/prism power as hand-to-hand combat power augmentations.

Pink Ranger
Emma chose this Ranger as one of her most powerful Legendary Modes. This Ranger generates hard light boots for powerful kicks.

Green Ranger
Jake unlocked this Ranger during one of his solo battles. This Ranger generates prism fists for powerful punches.

Was also used by Emma during the final battle with Levira.

Blitz Mode
The fourth power set the Rangers used was described as Powers of the Legendary Dragon.

Red Ranger
This Ranger had a motif of a Dragon. Troy was able to unlock this.

Blue Ranger
This Ranger had a motif of a Pegasus. Noah was able to unlock this.

White Ranger
This Ranger had a motif of a Mermaid. Gia was able to unlock this.

Pink Ranger
This Ranger had a motif of a Phoenix. Emma was able to unlock this.

Black Ranger
This Ranger had a motif of a Griffon. Used by Jake during the final battle with Levira. It was referred to as Blitz mode, a name Gia previously used for Maskman.

Yellow Ranger
This fifth power set was only used once by Gia during the final battle with Levira.

Red Ranger
Though Troy didn't use this power set to transform, he used it in the Legendary Megazord to activate its fire storm strike attack.

Behind the Scenes

 * All the "new power" sets are adapted from shows that were not adapted into Power Rangers, with a few of them coming from shows that came years before Kyōryū Sentai Zyuranger, which was adapted into the first ever Power Rangers show Mighty Morphin Power Rangers.
 * The first power set was adapted from the Dairangers of Gosei Sentai Dairanger. As it is also the source footage of Mighty Morphin Power Rangers (Season 2), the similarities between their suits and the White Ranger's and their relation to the Thunderzords is obvious to long-time watchers and is made even clearer when all six powers are used side by side in "The Perfect Storm". They may be referred to as "Legendary Squadron" or simply "Squadron" as the Legendary Mode is referred to as "Legendary Squadron Mode" with 'Squadron' being the only real insertion. However, their attack with their chakrams is referred to as "Legendary Strike".
 * The Red Ranger powers were derived from Ryo of the Heavenly Fire Star/RyuuRanger.
 * The Green Ranger powers were derived from Daigo of the Heavenly Phantom Star/ShishiRanger.
 * The Blue Ranger powers were derived from Shoji of the Heavenly Gravity Star/TenmaRanger.
 * The Yellow Ranger powers were derived from Kazu of the Heavenly Time Star/KirinRanger.
 * The Pink Ranger powers were derived from Rin of the Heavenly Wind Star/HououRanger.
 * The other four all appear to have been adapted due to a Gokai Change from Ep. 49: The Greatest Treasure in the Universe, where they were all used in the final battle with Insarn (used as Levira in Super Megaforce); only Sun Vulcan was not used, which instead was replaced by the original Red Ranger of Mighty Morphin' Power Rangers
 * Lightning was adapted from the Maskmen of Hikari Sentai Maskman.
 * The Yellow Ranger powers were derived from Haruka/Yellow Mask.
 * The Blue Ranger powers were derived from Akira/Blue Mask.
 * Prism was adapted from the Flashmen of Choushinsei Flashman. In "Power of Six", Jake mentioned how "flashy" his powers are.
 * The Green Ranger powers were derived from Dai/Green Flash.
 * The Pink Ranger powers were derived from Lou/Pink Flash.
 * Blitz was adapted from the Changemen of Dengeki Sentai Changeman.
 * The Red Ranger powers were derived from Hiryuu Tsurugi/ChangeDragon.

 * The Sentai counterpart of the Legendary Squadron was given the name Power Rangers Star Force in early casting sides for Power Rangers Super Megaforce.
 * This is somewhat in-line with the name Toei gave Dairanger years ago for international distribution, Star Rangers.
 * Of the sixteen powers, seven of them belonged to Rangers who guest starred on Gokaiger (Dai, Ryo, Shoji, Kazu, Akira, Shou, Remi).
 * In the tenth episode, The Perfect Storm, the rangers uses the first set of powers saying "Legendary Squadron Mode". Squadron is one of the English translations for Sentai.
 * Troy's and Emma's Legendary Squadron and Legendary Dragon forms share the same animal motifs as their base Megaforce powers, a dragon and a phoenix respectively.
 * When Gia morphs into Yellow Mask's counterpart in Samurai Surprise she says "Legendary Ranger Blitz", but when Noah transform into Blue Mask's counterpart in The Wrath he says "Lightning Mode: Blue!".
 * Blitz is the first Power Rangers team without a Yellow Ranger, making the Red Ranger and the Blue Ranger the only colors to appear in every team. The succeeding season will also feature a team without a Yellow Ranger, which makes the Red Ranger and the Blue Ranger the only colors to appear in every team.
