"Arrow" turns 100 on November 30, and to celebrate Oliver Queen (Stephen Amell) and company will team with the rest of The CW's superhero line-up, including The Flash (Grant Gustin) and Supergirl (Melissa Benoist), to fend off the Dominators, the alien race featured in the 1988-1989 DC Comics crossover “Invasion!”
The official synopsis for the series' centennial episode also offers insight into the return of a number of "Arrow" characters who are long dead. Are Oliver's father and mother truly back from the grave, or is it all part of a mind-control game played on the vigilante by the Dominators? The fact that Laurel Lance, who also died, is alive and Oliver's finance would indicate that to be the case, but there's also the possibility that Flashpoint's ripples are continuing to spread across the Arrowverse.
