Hi guys,
as some of you have mentioned before, a possible cameo of Cyclops was shown in X-men First Class. I decided to take a screen-shot from a release I found in internet.
The scene was shown when Charles used Cerebro for the first time. He saw the mutants in color, while the homo sapience were just in black and white. At some point during the scene he saw a black girl with white hair, which is believed to have been Storm. A few seconds after that we see another girl and on the background there is a boy with dark, kinda red sunglasses, who looks like Scott Summers. He also looks like he is playing baseball. I could be wrong, but didn’t Cyclops in X-men TAS have a flashback in which he discovered his powers during playing baseball?
So here is the picture:
