Fluke the Blue Whale

Big Fluke is a Mobian whale member of the Forty Fathom Freedom Fighters and perhaps the largest sea creature on Mobius. He assisted in the battle against Octobot, and flattened the mechanical octopus under his enormous bulk. (TMS: #1)

He later repeated his performance to deal with Pseudo Sonic, the Misfit Badniks and their island. (StH: #185)
