Summary

Undertale (also stylized as UnderTale or UNDERTALE) is a role-playing game developed and published by indie developer Toby Fox.

In Undertale, players control a human child who has climbed Mt. Ebott and fallen into the Underground: a large, secluded region underneath the surface of the Earth separated by a magic barrier. The inhabitants of the Underground are the monsters, a diverse group of non-humans who were banished there after a great war with the humans. A notable feature of the game is the degree to which your actions affect the world around you; practically all possible choices have an effect. A related game called Deltarune is in the works.

Power of the Verse

Every single monster that Frisk faces is Large Building level, because they are able to withstand multiple attacks from a medium determined Frisk, and are able to damage other monsters with superior stats. Due to humans being able to naturally produce Determination, they are naturally much stronger than monsters, reaching up to Town level with enough Determination. At the peak of the verse, characters are capable of affecting the entire setting of the game, reaching Multiverse level.

In terms of speed, the characters usually vary from Subsonic+ to Hypersonic, possibly Massively Hypersonic+, with Frisk being able to consistently dodge lightning and meteors, characters like Asgore upscale from these speed feats. Frisk can boost their speed even more so with items such as the sea tea, with only Sans and Flowey being on par with them. With the power of Determination, characters can reach Immeasurable, with empowered DT users like Frisk being able to outrun an entire timeline being consumed.

In terms of remarkable abilities, monsters are able to utilize Non-Physical Interaction, Soul Manipulation, Durability Negation, and Inorganic Physiology. Certain DT-infused monsters, more specifically the Amalgamates, have Invulnerability, Supernatural Willpower, Regeneration (High-Mid) and Immortality (Type 2 and 3). Humans have less magical abilities, but they are still capable of Sealing and Forcefield Creation, Supernatural Willpower, and have limited Invulnerability. Any creature with significant enough Determination can gain control of the timeline, granting Time Manipulation and Acausality (Type 1), although with enough DT they can achieve Immortality (Type 4) and Resurrection (Low-Godly), among others.

Calculations

Sans Moves Heavy Bones At High Speeds - 15483 Joules (Wall level)
Undyne Jumps To Save Monster Kid - 26795 Joules - (Wall level)
Chara Falls In a Hole - 40882 Joules - (Wall level)
Ice Cube Throw - 64383 Joules - (Wall level)
Pyrope's Bomb - 0.002 Tons of TNT - (Wall level)
Undyne's oven explodes - 0.008803 Tons of TNT (Small Building level)
Knight Knight Summons Meteors - 0.021 Tons of TNT - (Small Building level)
Mettaton Destroys Metal Wall - 0.024 Tons of TNT - (Small Building level)
Flowey moves an elevator at subsonic speeds - 0.072 Tons of TNT (Small Building level)
Ice Cap created large ice cones - 0.081 Tons of TNT (Small Building level)
Frisk no-sells an explosion that pulverizes a tree - 0.102500084 Tons of TNT (Small Building level)
Mettaton EX's supersonic kicks - 2.42 Tons of TNT (Large Building level)

Notes

The Check Stats in Undertale are canon due to them being referenced in-verse from multiple characters, and thus being viable for scaling.

ATK/DEF values from -12 to 17 are rated as downscaling from High 8-C (2.42 Tons of TNT), due to characters within said values, despite being weaker, being still roughly comparable to values higher than 18. An example are the Dogi (14 ATK/5 DEF each) being able to fight and take blows from Frisk, who in Showdin had enough Determination to harm and kill Jerry (30 DEF). Other showcases are Napstablook (10 ATK) being capable of harming Mad Dummy, who has 30 ATK and can take their own attacks, Lesser Dog (12 ATK/2 DEF), who could still harm and take Frisk's hits, or also Snowdrake's Mother (-12 ATK) who can still damage Frisk like Reaper Bird (9 ATK) does.

ATK/DEF values from 18 and up are rated as High 8-C (2.42 Tons of TNT) due to Mettaton EX (47 ATK/47 DEF) being able to attack with big metallic legs at supersonic speeds, and Undyne (50 ATK/20 DEF), who is stronger than him, being able to tank well attacks from a Frisk who can take her hits. Weaker characters who fit within said range have showcased to still be close to that level of power, an example being Papyrus (20 ATK/20 DEF), is still called very strong from Undyne. Other examples are also Muffet (38.8 ATK/18.8 DEF) who can take blows on a similar degree, or Woshua (18 ATK), who can fight alongside Aaron (24 ATK).

The full power of a single human SOUL is rated as 7-C (48.4 Kilotons of TNT) due to it containing enough power to match the entire Underground population.

Frisk Runs With Papyrus - 7.14 m/s - (Average Human)
Papyrus Runs Across His House - 16.92 m/s - (Superhuman)
Frisk dodges Barks - 197.35 m/s - (Subsonic+)
Frisk Dodges Meteors - Mach 4.40 (Supersonic+)
Frisk dodges lightning - Mach 3.05 (Supersonic+), possibly Mach 2414.68 (Massively Hypersonic+)
Tsunderplane outruns lightning - Mach 4.86 (Supersonic+), possibly Mach 3848.4 (Massively Hypersonic+)

Notes

The Subsonic+ characters such as Loox, Moldsmal, Lesser Dog and Greater Dog are scaled to Frisk's sound dodging feat. (197.35 m/s)
The most of the Supersonic+/Massively Hypersonic+ characters such as Papyrus, Astigmatism or Mettaton are scaled to Frisk's meteor dodging/Tsunderplane outrunning lightning. (Mach 4.86, possibly 3848.4)
Characters such as Asgore are Hypersonic/Massively Hypersonic+ through massively scaling above the aforementioned feats. (Mach 5, possibly 3848.4)
The fastest characters like Sans or Photoshop Flowey are scaled to Hypersonic+/Massively Hypersonic+ by scaling above Frisk's doubled speed with Sea Tea. (Mach 10, possibly 5302.24)

Frisk pushes a large rock - 443.189101424 Kg (Peak Human)
Ice Cube Lift - 2.42 Tons (Class 5)
Papyrus' Normal Attack - 5.38 Tons (Class 10)
Flowey moves an elevator at subsonic speeds - 36.5 Tons (Class 50)
Mettaton's big legs attack - 11,730.0534 Tons (Class M)

Notes

ATK values from 0 to 11 are scaled to Peak Human (443.189101424 Kg), due to a minimally determined Frisk with 0 ATK being able to push a large rock.
ATK values from 12 to 19 are scaled to Class 5 (2.42 Tons), due to Ice Wolf being able to lift and throw large ice cubes, and Lesser Dog (12 ATK) should at least be comparable to him due to being a part of the Royal Guard, which is described as being the elite military group.
ATK values from 20 and above are scaled to Class M (11,730.0534 Tons), due to Papyrus (20 ATK) being reffered as really strong from Undyne (50 ATK), a character who boasts about her lifting ability, making him not too far below Mettaton EX (42 ATK), who can attack using big legs.

Sans's Gaster Blasters - 18.14 m (Tens of Meters)
Sans' Teleportation - 1503.63660265 m (Kilometers)
Flowey's vines - 1879.35 m (Kilometers)

Do not attempt to make discussions regarding the speed of Vulkin's lightning attacks until new canon information is released from official sources, as this topic was repeated numerous times, and ultimately it was decided that the attack is ambigous enough to leave a possibility for it having actual lightning speed, due to Monsters' magic generally replicating its real counterpart without too many differences.
SOUL Power has been accepted as being an Universal Energy System, due to it being linked to the both the physical statistics and non-physical abilities of the user, other than it being able to be amplified through Magic and/or DETERMINATION (more info in this thread).
