Why does the 4th one look like Mystique from X-Men

Oh yeah it kinda does.

Especially since they made her hair red instead of pink.

Yea

It kind of a shame that the makeup and hair on the final Brainiac 5 suit are so cheap because the costume itself is fantastic.

Bruh that’s so low budget

Frankly prefer the hair and makeup given the full on green look. Plus he finally got the crown as of the finale.

It just look so much like paint and not like actual green skin.

Depends on the scene really.

I'm with bonki on this one, it did look like paint more than skin in all his scenes.
