Mamoru: It’s strange…(his hand glows) power is swelling up in me…It’s as if Chibiusa gave me the resolve I needed, she gave me her strength…and Hotaru gave me power too…
(His body goes transparent as he transforms)
Usako! I’m coming to help you too!
TUXEDO MASK DRAMATIC POSE

Yeah so for the record Mamoru TOTALLY had a naked transformation sequence in the manga. OBSERVE. Note that you can see the outline of his pecs the same way you can see the outlines of the Senshi’s curves. One panel and all transparent and ambiguous, but that’s how the Senshi’s transformations were in the manga- always restricted to one panel, with so much light you could barely even see the outline. I love this. TRANSFORMATION EQUALITY!
Also I love how he’s like “OMG CHIBIUSA AND HER GIRLFRIEND HAVE GIVEN ME THEIR AWESOME RESOLVE AND STRENGTH!” Manga Mamoru is fantastic like that, he’s always baldly admitting that he gets power and strength from the example of his girlfriend or daughter, and that he looks up to the ladies and they inspire him with their bravery. 
Also he is totally trying to me Batman here. And sparkling as he does it. MANGA MAMORU I WILL TAKE YOU OVER EDWARD CULLEN ANY DAY.
