Deltarune[]
In Deltarune Chapter 2, Kris is strong enough to rip out an iron shackle from a prison wall. I'll be calculating the force needed to perform this feat.
Calculation[]

We just need to find the cross section area of the chain's thinnest point.
Kris's Height = 162 px or 167.95 cm
Chain Diameter = 5 px or 5.18364 cm
Chain Radius = 5.18364/2 = 2.59182 cm or 0.0259182 m
Cross Section Area = Pi*0.02592^2 = 0.0021106677 m^2
The tensile strength of iron is 540 MPa.
Force = 5.4e8*0.0021106677 = 1139760.55 Newtons
Final Tally[]
Kris Breaks Shackles = 116.22 Tons of Force (Class K)
