Snowbarrisco

Snowbarrisco is the poly ship between Barry Allen, Caitlin Snow and Cisco Ramon from the The Flash fandom.

Season 1
Cisco met Caitlin and her then-boyfriend Ronnie when he became an employee of the same company that employed S.T.A.R. labs. Over time, they became best friends.

The labs created a particle accelerator whose explosion killed Ronnie and put Barry Allen a CSI into a coma. who was later admitted to S.T.A.R. Labs where Caitlin and Cisco continued to work. Upon awakening Barry discovered that he had gained super speed and that the explosion had also given the powers to other people who, however, used them badly. Eventually Barry decided to use his powers to stop them and find out who killed his mother and so Caitlin and Cisco became his support team.

In short, the three begin to meet even outside of work became good friends. After a while Barry and Cisco begin to suspect that the killer of Barry's mother is Dr. Wells, Caitlin and Cisco's boss who mentored Barry on how to use his speed. Initially Caitlin denies the accusations, but Barry manages to convince her to let them investigate. Soon the facts prove that the real Wells has been dead for years and that the person the team works with is the Reverse-Flash, a future enemy of Barry who went back in time and killed his mother.

However, due to the time paradox, Eobard Thawne (Reverse-Flash's real name) no longer had full access to his super speed and remained stuck in the past. He killed Wells and stole his identity in order to form the team and make Barry become the Flash. He could do it return to his time, and at the same time save his mother by resetting the timeline.

Barry initially accepts, but then reconsiders and it degenerates into a clash with Thawne which leads to the death of Eddie another member of the team who, as Eobard's ancestor, commits suicide trying to erase him from history, and to that of Ronnie, Caitlin's husband who sacrifices himself to close a black hole created by time travel. Everyone is devastated by the double mourning and Barry, feeling responsible for what happened, decides to dissolve the team, not wanting to endanger the surviving members as well.
