Dialga makes its first (and only) appearance in Pokémon Generations alongside Palkia and Giratina in episode 11. Using the power of the Red Chain, constructed by the gems of three Sinnoh Lake Pokémon, Cyrus brings forth the governor of time and the master of space. Cyrus commands that Dialga and Palkia end the world and begin it anew, in Cyrus' ideal image. Thanks to the Red Chain, Cyrus can make them do whatever bidding he desires. However, what Cyrus doesn't realize is that ending the world would cause a drastic shift in balance between our world and Giratina's realm. In the midst of bringing about the end, Cynthia, Sinnoh's Champion, arrives, Garchomp at the ready. However, she's too late; the end had already begun. Shortly after, Giratina arises from what seems to be a giant blob of black slime in his shape. Giratina uses Shadow Ball to break the Red Chains, thus freeing the lords of time and space from Cyrus' control and forcing them to return to their own dimensions.
