Powers and Abilities:

Superhuman Physical Characteristics, Magic (All monsters are made of magic), Personal Domain & BFR (When one encounters a monster they get into a fight, a FIGHT is an encounter in a monster's personal domain allowing them to fight humans, this has various rules such as turn-based combat), Creation (Monsters can make weapons, clothes and even food from magic), Limited Spatial Manipulation (Monsters can at times influence the battle box), Transmutation & Healing (Monsters can turn their attacks into healing projectiles), Absorption (Monsters and humans can absorb the SOUL as long as the person isn’t the same species as them), Danmaku (Shown here), Soul Manipulation & Essence Manipulation (All attacks in Undertale are to the SOUL), Resistance to Physical Attacks (All monsters bodies are attuned to their SOUL thus only attacks that can affect their SOUL can affect them), Soul Manipulation & Essence Manipulation (Can take hits to the SOUL)

Weapon Mastery (Skilled with swords and spears), Skilled in H2H combat (Trained by Asgore in hand to hand and weapons), Weapon Creation (Creates spears), Energy Manipulation, Velocity Manipulation (Can turn the SOUL green making the opponent unable to move, this extends to their physical body as they can not flee from fights), Resistance to Extreme Heats (Resisted the temperatures of the MTT Oven which is stated to heat over 9000 degrees Fahrenheit)

All previous powers and abilities, Regeneration (Low-Godly to Mid-Godly; Regenerated her body which is attuned to her SOUL)

Sheer Will (All holders with determination logically have large amounts of willpower), Statistics Amplification (Frisk used determination to continuously amp themselves to tank hits from Asriel's attacks and keep up with him in speed), Regeneration Negation (Up to Low-Godly to Mid-Godly; Genocide run Frisk was capable of permanently killing Undyne the Undying), Power Nullification (Passive. Anyone with higher determination then another can overrride their powers. The difference in DT allows them to nullify more abilities, though the standard is negating all time based abilities)

Standard Equipment: Spears

Intelligence: Genius (Leader of the Royal Guards and constantly held in high regard by people. A combatant trained by Asgore himself)

Weaknesses: Her armor can make her overheat in areas as hot as Hotland. All monsters are weak to an attack with killing intent behind it and if a monster doesn't want to fight, they are weakened greatly.

Key: Base | Undyne the Undying

Note: Despite Undyne having determination considering what it does to her body and how monsters are naturally not supposed to contain much determination it is very unlikely she has all the other abilities other determination users have even if there isn't another user with greater determination.

Explanations

Why attacking the SOUL is essence manipulation.
