Sometimes video game characters from different games look surprisingly similar.
Moira Burton and Abigail "Fetch" Walker
We don't know much about Moira Burton from Resident Evil Revelations 2 yet, but we have seen what she looks like and we can't help but be reminded of Infamous Second Son's Fetch. From the jacket to the torn pantyhose to the similar haircut the two seem to be getting clothing ideas from the same punk rockers.
Talion and Gabriel Belmont
It's really the haircut that makes these two look so similar. Also the medieval garb. If Talion appeared on the battlefield of Lords of Shadow, I wouldn't be surprised, and if Gabrielle showed up in Shadow of Mordor's Mordor, he wouldn't seem out of place. Also, you can write out the name of the two games like this: Casltevania: Lords of Shadow of Mordor. That has to count for something.
Bayonetta and Katherine McBride
Despite their radically different hair colors, I wouldn't be surprised to learn that these two are sisters. It's really the glasses more than anything else that makes them look similar. Glasses are genetic, I hear.
Limbo's nameless boy and Heartless
A short-in-stature creature with glowing eyes who looks like a silhouette could describe either of the characters seen above. And technically, with the ambiguous background of Limbo's nameless boy, he could be one of Kingdom Heart's heartless for all we know. This could be less of a case of two characters that look alike, and more of a case of two characters that are the same person (or thing).
