Arrowverse Crossover: 11 Best Moments From Arrow's 100th Episode 'Invasion!'

11. Cisco And Team Arrow

The overall subplot involving Cisco working with Team Arrow wasn't all that interesting - the villain was particularly unmemorable and ultimately felt pointless - but it did give us a couple of fun moments.

This was where the crossover spirit really continued, and the first spark of that was Cisco coming in to work with Team Arrow.

Having spent most of The Flash episode still dealing with his resentment towards Barry (understandably so), being on Arrow frees him up to get back to his old self. He works particularly well with Felicity, but also has a couple of strong moments with both Wild Dog (the way he says "hi" when the vigilante is glaring at him) and Curtis ("your tech guy references movies? How original.").
