I’d say no one has the right to decide that. Beauty truly is in the eye of the beholder. Which brings us to today’s quote by Magneto to Mystique in X-Men: First Class.
“If you’re using half your concentration to look normal, then you’re only half paying attention to whatever else you’re doing.” – Magneto says this to Mystique.
For those of you who don’t know, Mystique is a super-powered being and her power allows her to look like anyone. But her natural appearance is dark blue skin and red hair. Now in this movie she is insecure about her appearance because it scares people. So she uses her powers to always look like a normal human being and Magneto rightfully points out that if she is constantly spending so much of her attention on how she looks, then she won’t be able to focus on anything else. Which makes her realize that she should be proud of how she looks and just keep it natural. She understands that she should only use her powers when the situation actually calls for impersonating someone.
