Tidal Whale

Tidal Whale, also called Tidal Makkoeen, is a character who appears in the Mega Man comic series published by Archie Comics. He is a whale-based reploid that existed during the 21XX era. He briefly appeared as a member of Sigma's Army during the Worlds Unite comic crossover.

Worlds Unite
Tidal Whale was revived by Sigma during the events of Worlds Unite as a part of Sigma's Army. When Sigma grew into his Sigma-2 form, he brought out Tidal Whale and all of the other mavericks from the past to fight against the Unified Army at the Lost Hex. Tidal Whale would later be seen in the world of Skies of Arcadia, facing against the Blue Rouges where it would be eventually destroyed by the combined efforts of the team.

Trivia

 * Tidal Whale is better known by his American name, "Duff McWhalen," and was mistakenly named "Tidal Makkoeen" in Sonic Universe #78. Writer Ian Flynn clarified that he meant to change "Tidal Makkoeen" to "Tidal Whale" at the last minute, but he guesses it was "too late."
