Qは瞬時にエネルギー転換と瞬間移動を行う能力を持ち、不死身であり全知全能の能力を有する。また、時間も自由に操ることができ、過去も未来も自在に行き来できる。彼らの能力は物理の法則を超越しており[[小惑星]]や[[恒星|星]]を動かすことも容易に出来、[[別の時間軸]]を作り出すことも可能であった。しかし、その全知全能の能力を有するQであっても、連続体によってその力を奪われるとすべての能力を失う。([[TNG:DE JA Q]]、{{TNG|運命の分かれ道}}、{{TNG|永遠への旅}})
Later on, the new Q became an intergalactic troublemaker. He started wars between innocent races, knocked planets out of [[orbit]], detonated [[Omega molecule]]s, and created havoc in every way he could. His mother disowned him, humiliated by his actions. Q, however, followed him, cleaning up all the damage.
Under advice from Janeway, Q implemented punishment on the boy. Q dumped him on ''Voyager'', and with the help of the "Q government" took away his powers. [[Q (Junior)|Junior]], as he was called by his father, had one week to become a good citizen, or he would be sentenced to eternity as an [[Oprelian amoeba]]. Junior did well for the first few days, until he stole the ''[[Delta Flyer]]''. After his friend [[Icheb]] was injured, however, he returned to ''Voyager''. Janeway made him apologize to the ship he attacked, which was in fact Q, who masqueraded as a likely target to test his son's attitude.
When Judgment Day came, Junior was still found unworthy of being a Q, but was good enough to be a Human. After this sentence, Q threatened to leave the Continuum unless his son was allowed to stay. After further pleading, the Continuum agreed to grant the young Q's powers back to him on the condition that his father act as his guardian and supervisor ''in perpetuum'', or at least until he could prove himself worthy.
