Star Trek creator Gene Roddenberry was born on this day in 1921. We have him to thank for numerous hours of entertainment and arguments over which movie was the worst. To celebrate Roddenberry’s awesome work, we’re going to be bringing you galleries of Star Trek cosplay all week, starting with the pictures below. Set phasers to “appreciate”.

And don’t forget to check out the other galleries:

Day Two gallery available HERE.

Day Three gallery available HERE.
