The Large Hadron Collider is at the high-energy frontier of particle physics, having produced proton$-$proton collisions during Run 2, from 2015 to 2018, at an unprecedented centre-of-mass energy of 13 TeV. The ATLAS experiment has a broad programme to thoroughly explore this uncharted territory, to seek out new exotic particles predicted by theories that boldly go beyond the Standard Model. Although the Standard Model has been very successful, it leaves many questions unanswered, prompting novel ideas about particles that could be hiding in the data, waiting to be discovered by intrepid explorers. These include dark-matter candidates, hidden-sector particles, new vector resonances, leptoquarks, and vector-like quarks, to name a few examples. Searches for new particles are reported here, with the exception of searches for supersymmetry or extended Higgs sectors as these are the subjects of separate reports.
