Ottawa ComicCon topped off eight weeks of planned guest announcements today with so much awesomesauce I am derpy-fan-girling all over the place.
Jonathan Frakes (Commander William Riker) and Marina Sirtis (Counselor Deanna Troi) from Star Trek: TNG will be making an appearance at the Con, as is Walter Koenig (Ensign Chekov) from Star Trek: TOS.
There are also as-yet-unrevealed plans for a special event at OCC featuring Walter Koenig and the wonderful Nichelle Nichols (Lieutenant Uhura, Star Trek: TOS), which I am very excited about, and once more details are known, of course I will post them here to share with all of you!

Fun Fact: Marina Sirtis very much wants to become the first female Doctor. If you agree, then please take a moment to sign the online petition: Marina Sirtis for the Doctor!
