Bowser is all manner of sizes all of the time - he was a giant when using the Power Stars in Mario Galaxy 2, he's several feet taller than Mario in 3D Land, etc. - but is most frequently depicted to be about twice Mario's size; and if you compare Ganondorf's size in Brawl to his size in Twilight Princess while using Link as a reference, you'll see that he's actually pretty accurate in size. And though you're right about Olimar and Lucario, those characters are being sized up, so we should probably treat them as separate cases.

In addition, we've already confirmed that Sakurai tends to be a bit of a Rickroll every now and again, yes; however, you don't really seem to be naming anyone ELSE that could possibly own a shadow in the Pyrosphere stage - a location where Ridley is fought in Metroid: Other M. (And don't give me any of that "the Ridley fought there is a clone" junk, because it's still technically the same creature, even if it's a different incarnation.) The context is right, the shadow matches, and there aren't any other giant space lizards claiming the shadow as theirs...
