expression, godan verb (-ru)
become reversed; become inverted; be turned around
Describes a situation, order, position, or relationship becoming the opposite of what it was or what is expected.
立場が逆になった。

逆にする is transitive, meaning 'to reverse something' deliberately, while 逆になる is intransitive, meaning 'to become reversed' on its own.
逆転する often implies a dramatic reversal or turnaround, especially in competition or fortune, whereas 逆になる is a more general and neutral expression for something becoming opposite.
Compound of 逆 (gyaku, 'reverse, opposite') + に (ni, adverbial particle) + なる (naru, 'to become'). The expression follows a common pattern of noun/adjectival noun + になる to indicate a change of state.
