This depends on what you mean by "bring communism."
In one sense, Lenin was the one who brought communism to Russia. He was the one who founded the Russian Communist Party. He was the one who led the Bolshevik Revolution that led to the Communist takeover of Russia and the creation of the Soviet Union.
In another sense, Lenin did not bring communism to Russia. The ideas of communism had made it to Russia after Karl Marx first expounded them. In 1893, for example, Lenin joined a group that was based on Marxist principles. This means that the ideas of communism were already in Russia.
So, Lenin was not the one to introduce the whole idea of communism to Russia, but he played the central role in making Russia into a communist country.
