Not really.

Perhaps in WWII. But that's one war and they were on opposite sides for other reasons.

Definition of fascism: a political philosophy, movement, or regime (such as that of the Fascisti) that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation, and forcible suppression of opposition

Definition of communism 1a: a system in which goods are owned in common and are available to all as needed b: a theory advocating elimination of private property 2capitalized a: a doctrine based on revolutionary Marxian socialism and Marxism-Leninism that was the official ideology of the U.S.S.R. b: a totalitarian system of government in which a single authoritarian party controls state-owned means of production c: a final stage of society in Marxist theory in which the state has withered away and economic goods are distributed equitably d: communist systems collectively

Communism and Fascism are not mutually exclusive. They are not antonyms. Forget all the lies you were told in government schools about these being opposite ends of a false linear paradigm.

They both utilize regimes, put the collective over the individual, use centralized autocratic government authoritarianism, lead to dictatorial rule, lead to severe economic and social regimentation, forcible suppression of opposition, lead to totalitarianism.

And forget the nonsense about goods owned by the common people. That never actually happened in any communist system in real life in real world history.
