Since AdventNEON is inspired by not only Sonic, but Mega Man. I had the idea to make a character similar to Roll, the close companion and sister of Mega Man. Thus, Aura was built.

Strengths: Combat skills, Her resonance, Super sonic scream, Can enter max mode like Neon if her power is 100% maximum

Weaknesses: Can get damaged when she gets out of the max mode, Her jetpack would ran out of energy, but can recharge, 

Likes: J-Pop/EDM music, Girly things, Cute things, Y2K, Rhythm Games, VOCALOID music, Shoujo Anime, Webcore, Scenecore, Kawaii, Singing, Helping out Neon, Oganesson, Her creator

Dislikes: Robocops, Getting in Trouble, Bad guys, Prof. Franca, Any haywire robocops, Bullies, Getting damaged, accidents, When Neon is in a huge distress, Getting lost

Aura is a Synthezoid who was created by Oganesson's friend and classmate, who is a supportive companion and close friend of Neon. She is the assistant of Neon who always helps him out even when he's in distress. Like Neon, Aura uses the power of her resonance to overpower and adapt to their enemies. If her power is maximum, she can enter max mode like neon, Her Miku-like pigtails became flowing and spikey and her entire max mode color is magenta/cerise. Her jetpack is equippable which whenever she takes flight, the jetpack leaves a pink, glowing trail. She wields a magical girl-esque wands that shoots out a sparkling laser beams and even heals the damage. Dreaming of becoming an android idol, she loves J-Pop/EDM music and even loves to sing. Aura is optimistic and energetic, but she is a tough and brave Synthezoid and will protect Neon the way she can even when he's distress. Her design is inspired by Ulala from Space Channel 5 and Hatsune Miku from VOCALOID and the Y2K Aesthestic.

So, what do you think of my first AdventNEON OC?
