As a Pet-Class Angeloid, Ikaros carries the powerful Transport Card (a summoning device that delivers whatever she orders to her location from Synapse). The original card she carried at the beginning of the story allowed for her to use only one card to summon items, but after it gets lost when she reverses the wild misadventure of Tomoki, she has to use an older model that only allows for one request per card. As the story progresses, it is revealed that Ikaros is more than just a mere Pet-Class Angeloid, but she is really a mighty Strategic Battle-Class: Type-Alpha Angeloid (the most powerful of the 1st Generation Angeloid models). She has an ultimate battle mode by the name of Uranus Queen, which allows her to unlock her full power potential and grants her access to incredible weapons to use in battle. When she triggers her Uranus Queen mode, her green eyes turn red, her soft, pink wings change into a bright light, and a golden halo appears above her head.
When in Uranus Queen mode, Ikaros has access to four powerful weapons/abilities that make her almost unstoppable on the battlefield. Her shield, the incredible Aegis Shield, can block almost any attack from every direction and make her almost immortal when it is successfully deployed. She gains the use of the might Apollon Bow, a silver bow that creates powerful energy arrows so strong, they could wipe out the entire nation of Japan in one shot when fully charged. The strong and deadly Artemis Launcher allows for her to launch dozens of powerful homing missiles of energy from her wings. And when all else fails, she can summon a colossal space warship by the name of Hephaestus, which is armed with massive energy cannons that when combined into a single shot, fires a beam so powerful that it could literally shatter the Earth on impact. In the manga, Hephaestus is a giant cannon that fires a straight wide laser beam, though seemingly having the power of the warship.Also this is Ikaros.

Gee wouldn't John be in for a shock if he met Ikaros, and learned what she was capable of. Though he would easily be able to handle things if he met her. I also doubt he would be surprised if he learned about her combat abilities. He would just try to prevent her from doing extremely dangerous.
Good thing ATWAG only allows game characters, and the occasional OC...
Also good thing that Ikaros is a protagonist within the series. Ikaros is usually a calm but resorts to violence if she sees that her master, Tomoki is in danger. She is fiercely loyal to Tomoki and does anything to please him.
She also has a hard time showing any emotions. As it's said that her combat capabilities, and computational abilities are extremely high, but her emotional control is low. Which is the reason why she usually can come off as emotionless. Though I haven't finished the manga, and the anime ends at the Chaos Arc. The manga is also still ongoing I believe.
