The Higgsplosion is a newly (2017) proposed mechanism by Valentin V. Khoze and Michael Spannowsky that can happen at high multiplicity inside a quantum field theory. This presentation aims to introduce the path for the Higgsplosion proposal and then explore some consequences of this mechanism. I will review some perturbative results of high multiplicity processes, discuss different approximations in this regime and the apparent loss of unitarity. Then, to rescue unitarity, Higgsplosion is introduced in a simple scalar field theory. In the end, I will discuss some open questions about this mechanism and present a different interpretation of what is happening if Higgsplosion occurs in the toy model presented.
