"Arrow" is set to celebrate its 100th-episode milestone and what better way to get the party started than with Oliver's (Stephen Amell) other superhero pals in The CW's DC Universe.

The upcoming spectacle titled "Invasion!" will continue the ongoing four-way crossover in the small screen with "The Flash," "Supergirl," "Legends of Tomorrow" and "Arrow" tackling an interwoven plotline.

Next week, the heroes are set to step into the world of Starling City's most notorious vigilante. Spoilers suggest that Oliver wakes up to a new reality where everything seems picture-perfect on the surface. 

The story revolves around a version of his life where he never got on The Queen's Gambit and with Robert (Jamey Sheridan) and Moira (Susanna Thompson) both alive and well. Completing Oliver's supposedly perfect life is his upcoming wedding with his fiancée, Laurel, (Katie Cassidy). Unfortunately, as he tries to grapple with this new and arguably more favorable life, Oliver starts to notice a couple of flaws which will ultimately push him to question how everything came to be.

Meanwhile, Felicity (Emily Bett Rickards) and the team will have their hands full with a new threat. Luckily, they get some much-needed help from The Flash (Grant Gustin) and Supergirl (Melissa Benoist).

In light of the pioneering show for the ever-expanding DCverse on TV celebrating its 100th episode, the conversation regarding its end is slowly creeping up in the online community.

"One of the things we embrace on the show is he's a hypocrite, he's kind of a lousy leader, he makes terrible decisions. It gives us fodder for a lot of stories," Marc Guggenheim, executive producer and co-creator of "Arrow," spilled to Entertainment Weekly when the media outlet raised the question. "[But] in season 5, we're probably telling more stories about the conflicting moralities of what Oliver's been doing over the life of the series. Everything we've been trying to do in season 5 has been building off of our history, our long history, because that's something that the other shows just can't do."

In hindsight, it seems like there is still a mapped plan laid out beyond the current season of "Arrow" and it might not be a bad thing to bring Oliver to a more in-depth full circle. But it is also no secret that there have been some unstable moments in terms of storytelling for the show as a whole. So should the series continue for a couple more seasons, fans hope that it will not be too much of a roller coaster ride in terms of narrative.

"Arrow" season 5 airs every Wednesday, 8 p.m. ET on The CW.
