It should come as no surprise that the majority of the Arrowverse’s best fighters come from Arrow, a show where the titular hero has to fight his way out of situations more often than not. There are a couple of surprises, though, as being a Legend also means getting one’s hands dirty from time to time.
10) Ricardo Diaz

Growing up in Star City, Ricardo Diaz knows all about fighting for survival. He starts to make a name for himself in Arrow Season 6, building a drug operation that threatens to throw the city into chaos. Oliver Queen challenges Diaz because he doesn’t believe he’s much of a threat, but the villain proves that living on the streets can teach someone just as much as the League of Assassins.
9) Heatwave

Mick Rory starts out as a small-time villain on The Flash, working alongside Leonard Snart. His heat gun causes trouble for Team Flash, but they come up with a solution pretty quickly. While Mick still relies on his weapon when he joins the Legends of Tomorrow, he’s not afraid to throw down if the occasion calls for it, punching aliens and demons without a second thought.
8) Prometheus

When Adrian Chase infiltrates the mayor’s office in Arrow Season 5, his goal is to break Oliver Queen. He achieves this by forcing the hero to confront his past and the fact that he takes pleasure in killing. However, Chase gets a few licks in as well, and since he was trained by Talia al Ghul, the daughter of the Demon’s Head, they pack a serious punch.
7) Malcolm Merlyn

The first Big Bad that Oliver comes up against is his best friend’s dad, Malcolm Merlyn. Like Prometheus, Merlyn has experience with the League of Assassins, making him an incredibly skilled fighter. Oliver beats Merlyn in Season 1, but he teams up with him later on because he knows how dangerous the villain is in a fight.
6) Deathstroke

Oliver doesn’t have much of a chance when he washes up on Lian Yu. The only way he survives is by learning from the other people stranded on the island, including Slade Wilson. Unfortunately, Oliver has to turn on Slade when he loses his mind, seemingly killing him. Slade later returns as Deathstroke and uses his military background, as well as the Mirakuruย coursing through his veins, to give Oliver fits.
