Agents of SHIELD's Ruby is the Anti-Spider-Man

returned to present day, only to run into Ruby, a mysterious new enemy unlike any they have encountered before.

S.H.I.E.L.D., the world's wanted fugitives - Ruby was absorbed by whatever was playing on her mobile device when we first meet her. She was flippant and rude to her mother, and she was in trouble for skipping out on her classes. But Ruby was also obviously intelligent, especially when she questioned the general about whether she was "a good guy". Ruby goes even further, pointedly asking her mother, "Are you sure you're not a bad guy?" We quickly learned the answer to that very question about Ruby: Clad in a mask and costume, Ruby led a strike team against Coulson's Agents. Even worse, Ruby used her razor-sharp chakram to shockingly slice off both of Yo-Yo Rodriguez's arms!

the most powerful Inhuman in the MCU. However, Ruby's vicious attack on Daisy's friends shows that her hero worship of Quake has a sinister edge to it. Ruby was even disappointed Quake wasn't present when she confronted S.H.I.E.L.D. There's no telling what harm Ruby might have done to her 'hero' had they met.

Though answers to the many questions fans have about Ruby are surely coming in the episodes ahead, we can already surmise that Ruby is a much darker take on a teenager in the MCU, especially compared to Peter Parker and his high school chums. Despite her musing over whether General Hale is good or bad, Ruby's own moral com is totally out of whack. Ruby seems to have been raised in isolation and trained to kill by her mother. How she turned out the way she did could be a combination of both nature and nurture, but she's definitely a deadly threat to S.H.I.E.L.D. Ruby has not only permanently disfigured Yo-Yo, she doesn't feel the slightest bit of remorse about it.

Whether or not it's her upbringing to blame or if Ruby is really just a rotten apple at the core, she is a stark contrast to the other teenagers the MCU has introduced so far. Peter Parker and even the group of friends in The Runaways have sound, heroic moral comes. They struggle to do what's right, at a great personal cost to them. The Runaways even turn their back on their parents because they morally oppose the evil the elder generation is complicit in. Peter, meanwhile, is famously driven by his moral code of great power equating great responsibility. Ruby is their opposite number. She is as deadly as Sinara, Kasius' Kree assassin in the future, but with the youthful face of an angel.

Even more than Wanda Maximoff when the Scarlet Witch was a briefly a villain, Ruby is the MCU's first scary teen. She is definitely no do-gooder like Spider-Man - Ruby is a killer. It remains to be seen what exactly Ruby has in store for Quake when Daisy meets her 'biggest fan', but Agents of S.H.I.E.L.D. fans can be sure Ruby's not interested in a selfie and Quake's autograph.
