Twivine Sparkle and Lady Tirek

[Name: Twivine Sparkle

Nicknames: Princess Twivine Sparkle

Appearance: Twivine has 4 hooves and no arms, like all equines. She is a purple alicorn with bangs who looks similar to Twilight Sparkle. Like all alicorns, she has pegasus wings, and a unicorn horn. Her mane and tail are black with a green and dark purple streak. She has maroon, cat-like eyes with green glowing sclera which are constantly flowing with wisps of dark magic. Her Cutie Mark is a 6-pointed star surrounded by six smaller stars, the same as Twilight but with the colours inverted to black and green.

She wears metallic black regalia with green gems, consisting of a crown, peytral, and hoof shoes.

Abilities: Twivine Sparkle can absorb and utilise the magic of others, including other Alicorns. She can also control Plundervines, which are indestructable black brambles with anti-magic properties. She can teleport, fire magic lasers, fly, use telekinesis, and other types of powerful magic. Her strongest ability is a copy of Twilight's "Rainbow Power", which can warp reality and overpower powerful creatures. It takes the form of a colour inverted rainbow.

In her ultimate form, Tirevine Sparkle, she takes the form of a giant centaur. This form is a last resort, but boosts her power significantly.

Backstory: Twivine was created initially when Twilight Sparkle was overpowered and corrupted by Plundervines as she attempted to save the Tree of Harmony from their influence. She created a clone of herself in the Mirror Pool before eventually being restored by her friends.

This Mirror Pool clone of Twivine Sparkle roamed Equestria, stealing magic from other powerful ponies and creatures. She created Lady Tirek from Tirek's DNA, but Lady Tirek betrayed her, seeking to claim Equestria for herself.

Personality: Previously, Twivine was a power-hungry villain who simply wanted to absorb and stockpile magic to conquer Equestria.

However, she has switched sides against Lady Tirek. She is starting to genuinely understand the power of Friendship, and beginning to believe in it despite her previous dismissal of it.

She has a deep fondness for Equestria, which was the root of her desire to conquer it. However, she is still battling darker thoughts of stealing power and becoming stronger. Therefore, she is confused and unsure of her place in the world, but still hopes to be fully redeemed and truly join the side of good. ]

[Name: Lady Tirek.

Appearance: Lady Tirek is a roughly 8 metre tall centaur. Her lower half is a black horse, her upper half is a red-skinned woman with black armour, white hair, and black eyes with yellow irises. She has a two large black horns.

Abilities: Lady Tirek has powers like her creator: she can absorb and stockpile magic power. With her stolen power, she can use energy beams, orange energy orbs, telekinesis, super strength, teleportation, and flight. She grows larger with the more power she steals.

Backstory: Lady Tirek was created by Twivine Sparkle to be her ultimate weapon: a clone of Lord Tirek who she hoped would obey her. However, Lady Tirek hated this idea and immediately betrayed Twivine.

Personality: Lady Tirek is powerful, domineering, obsessed with power and control, and believe all of Equestria should belong to her, and her alone. She will use any tactic to gain power, from brute strength to deception, and holds a low opinion of everyone around her. She views kindness, compassion, and honesty and weaknesses, and will betray, destoy, and absorb the magic of anyone she views as lesser than her.
