What type of energy is the e in mass–energy equivalence equation?

[Esoremada]

We recently started learning about special relativity. Today my teacher said that E_T = E₀ + E_K when talking about masses in motion. So what is the name for the energy stored in mass? We have already learned about kinetic, gravitational, elastic, magnetic and I'm sure I forgot a few.

Rest Energy:

$E_0=m_0\,c^2$

Alright, thank you. Idk how I couldn't find that :P
