Multiple Princess Tier
Description and Requisites: Character or characters are capable of fighting on even terms with multiple Princess characters. Usually such a character is level with Triek in terms of power.

Celestia & Luna: Being the two primary Princesses causes these characters to be the bar setters for this tier. Both Princesses using the elements of harmony transcends this tier, however this likely will not be seen due to Luna's banishment.

Discord: Spirit of chaos and disharmony, easily the strongest character prior to Triek's introduction, and as Starlight's alternative timeline indicates capable of besting Celestia and Luna when the pair are not using the elements of harmony.

Triek: When powered up or energized, Triek is capable of defeating multiple princesses, and possibly defeating Discord. His only defeat in the show happening when he was defeated by an empowered Twilight Sparkle, using powers from multiple princesses.

Empowered Twilight Sparkle: When using the powers of other princesses or empowered through other means, Twilight Sparkle was capable of holding her own against Triek.

The Mane 6, Elements of Harmony: Utilizing the elements of harmony, the protagonists of the show have been able to reseal Discord, indicating that when working together they are capable in the same ways the original Princesses are.

Rat-Trap: Capable of holding his own against Inari and a weakened Celestia, Rat Trap is a member of this tier and an excellent contender for the higher slots.

Princess Tier
Description and Requisites: Character or characters are capable of fighting on even terms with a single Princess character.

Celestia: The Solar Princess, and hence an obvious character for this tier. Celestia is likely not the most powerful character at this tier, due to her defeat at the hooves of other characters who sit at this tier, notably Nightmare Moon.

Luna: As the Lunar Princess, Luna has a spot at this tier, even though her full powers have not been explored in the show. Her dialog hinted that she was capable of defeating Sombra, or at least fighting him on even footing during the season three opener.

Twilight Sparkle: The newest Princess and the element of magic, Twilight Sparkle is capable of using an impressive amount of magic, unprepared and at will, something that sets her above Starlight Glimmer, and sets her in this tier, even though she is one of the weaker participants. She still sits in good company.

Shining Armor and Princess Cadance: While both of these ponies are not the most talented in terms of magical ability, their display at the Season two closing indicates that when paired together, they are far more than the sum of their parts. This multiplicative factor also happens during the Season three opener, which places them on par with Sombra, if not higher.

Empowered Chrysalis: Despite not being the most powerful character, Queen Chrysalis was capable of defeating Princess Celestia after feeding off of Shining Armor's love for his wife, making her a force to be reckoned with on a good day.

Nightmare Moon: Nightmare moon is fully capable of fighting Celestia on even footing, as the elder sister had to use the elements of harmony to banish the younger. Otherwise she has not been very much explored.

Sombra: As indicated by his fight with Shining Armor, and his defeat due to the Crystal Heart, Sombra does have a significant of magical talent, even if the full extent of his powers has not entirely been defined.

Orbit: Despite most indicators, Captain Orbit is capable of fielding some impressive power, and while it has not been fully expanded on and has been hinted at, Orbit likely can field enough firepower to put him on par with a Princess.

Sea-going Goldfin: Goldfin is arguably the most dangerous pony in the sea, being able to move extremely fast, while also sporting incredible strength, both physically and magically. Her ability to control sea creatures adds to this, and sets her comfortably in this tier.

Power Ponies: Despite not having the incredible synergy Shining Armor and Princess Cadance have, both sets of power ponies can field an incredible amount of utility, even if they aren't as strong per-say as the other members of this tier.

Princess Parlys: Effectively ascending to this tier is the changeling mage. He has exhibited a great amount of magical knowledge, allowing him to throw around a great amount of weight. However his true strength is his guile, which solidifies him at this tier.

Inari: While not as strong as other members of this tier, Inari possibly has the most extensive knowledge base as depicted so far, which sets her in this tier, allowing her to fight at an impressive level.

Sub-Princess
Description and Requisites: Powerful characters who are not Princess tier characters either in terms of raw power, or other reasons.

Princess Cadence: This princess on her own isn't incredibly powerful, but as an Alicorn, she has several skills, and is likely proficient on most fields of magic.

Ironworks: Lots of utility, and a significant amount of power behind it. Most of his strength comes from very specific applications of his magic such as soul tearing, or tele-fragging but uses his extensive amount of utility to make up for it, delving into alchemy, forging, construction, among many other fields.

Goldenheart: Having a significant amount of power, and rather fond of flashing it around, Goldenheart has access to her father's knowledge, which makes her an unpredictable force at the best of times.

Flashfire: One of the other heavy hitters of the Power Ponies, this dragon's super strength and fire powers gives her potent offensive powers, while her durability gives her solid staying power, even if she isn't the most mobile of the team.

Impressive Ponies
Description and Requisites: These characters are capable, but sit well below the powerful characters of the first two tiers. Each of the characters at the Princess tier likely can fight multiple members at this tier without too much trouble.

Decibelle: The medic of the Power Ponies, she also possess a surprising amount of utility in her voice mimicry, along with her auditory assault.

Glaive: One of the more agile and thoughtful members of the Power Ponies, Glaive can field an impressive amount of equipment. His abilities at stealth, and assassination put him at the upper end of this tier, and would put him at the Sub-Princess Tier if he wasn't so reliant on his physical capabilities.

Strongheart: While not the most powerful pony, Strongheart is capable with his weapons, and offers some utility in the form of AVERI, along with capable magic usage. He does lack the staying power to place him higher, often not thinking decisions through or accounting for secondary steps.

Phantomenia: A quite agile Phoenix, Phantomenia can gather useful knowledge due to her emotional intuition, while also allowing ponies to fight at their best. On her own, she is far less dangerous, and relies on her defensive abilities to isolate and defeat individual targets.

Dazzling Light: Quick to emotion, Dazzling Light can field a fiery display, but like Strongheart is quick to go down after a few blows, offering her less staying power than Flashfire provides, but her increased mobility offers her a more agile spot on the Power Pony team.
