Mutual annihilation is the term we usually apply in physics to the combining of a particle and its antiparticle. Under the circumstances, the particles are completely converted into energy. That is, their entire mass is converted into electromagnetic energy. Let's look a bit more closely.
What we usually encounter is mutual annihilation events in the form of positrons interacting with electrons. The positron is the anti-particle of the electron, and shortly after the creation of the positron (either in beta plus nuclear decay or pair production), the positron will "combine" with an electron, and both particles will be completely converted into energy. This energy appears in the form of two energetic gamma rays going in opposite directions. Each gamma ray has an energy of about 0.511 MeV, or more, depending on the kinetic energy of the positron and electron that interact to release them. Links can be found below for more information.
If a quark and anti-quark collide, they could scatter. But it is also possible (with increasing probability at lower energies) that they undergo what is called mutual annihilation. In mutual annihilation, both particles are converted entirely into energy. Quarks, it should be noted, cannot exist by themselves. It should also be noted that there are some particles created by quark-antiquark pairs. These particles, like the J/psi meson, are short-lived, but do exist. Investigators are still working on a better understanding of quarks and the relationship between the strong, weak and electromagnetic interactions.
Positrons are short-lived because they are the antimatter counterpart of electrons, leading to annihilation when they interact with electrons. This annihilation results in the conversion of their mass into energy, in the form of gamma rays. As a result, positrons have a very short lifespan before they collide with an electron and cease to exist.
They developed a mutual friendship.
World annihilation comes to mind.
Gamma rays are produced when a positron emitted by a radioactive tracer in the body collides with an electron, resulting in annihilation. This annihilation produces two gamma rays which are detected by the PET scanner to create an image of metabolic activity in the body. Detected gamma rays help determine the location and concentration of the radioactive tracer, allowing for visualization of physiological processes.
The alternatives are either annihilation (possibly mutual) or taking to the hills to carry on guerrilla combat, perhaps for years.

Total Annihilation happened in 1997.
Celebration of Annihilation was created in 1996.
"Annihilation" by Jeff VanderMeer has for around 195 pages.
Assimilation and annihilation are both controversial methods for promoting unity among diverse groups. Assimilation involves integrating different cultures into a dominant one, while annihilation seeks to eliminate differences altogether. However, assimilation is generally considered more effective in fostering unity and understanding, as it allows for the preservation of cultural identities while promoting cooperation and mutual respect. Annihilation, on the other hand, can lead to conflict, resentment, and the loss of valuable diversity.
