Mega Gyarados does not look good at all. I can't help but look at it thinking it has some kind of disease. Its all swollen up, and those red bulges along the side of it do not look healthy. They look like blisters or unnatural growths perhaps filled with pus. The Gyarados itself looks bloated and that you could perhaps burst the thing.
Now I am sorry, but humans have a natural aversion to things that do not look healthy. I can't understand why they designed it to look so, awful and nasty. It seriously looks to me, like a bloated Gyarados with red, pus filled nodules running down the side.
urp *throws up everywhere*
