Summary
Inspired by the Absolute Ben 10 fan comics by DuckSenile, and the original Marvel Ultimate comics, my take on the Ben 10 series if it got the original Marvel Ultimate comics treatment.
“It started when an alien device did what it did. It wrapped itself upon his hand with secrets that it hid. Now he’s got superpowers, he’s no ordinary kid. He’s Ben 10.”
During summer break, 13 year old cousins Ben and Gwen Tennyson, go with their Grandpa Max on a summerlong roadtrip across the country. During a night out on camping, Ben accidentally comes across a mysterious meteorite that contained a device which then leapt out and attached itself permanently to his hand. Armed with this unknown alien device, Ben must now unlock its secrets and learn how to control it before forces from beyond and on Earth go after him and the device.

Summary
When Mirabel was ten, she found the Omnitrix and became the shapeshifting-powerhouse hero, Shifter. And for five years, she's been a hero, until she decided to go for a normal life and retired from wearing the Omnitrix. Although you've been retired, there are still moments when people remember the shapeshifting heroine who helped save cities and people from super villains. You were practically the first superhero ever.
Now at 23 years old, Mirabel feels like she's wasted the last three years on a loveless relationship with Barry Allen, AKA The Flash. Barry asked you out while Iris was still dating Eddie. Years later, it's obvious that he'd rather be with her, but he just won't admit it or let you go. This has been killing you for years, and Savitar has pushed you past the point of no return- there is no ignoring the situation, your heartbreak, anymore.
Mirabel now has that chance once more when Azmuth comes to her for a mission in space and to be prepared for a threat bigger than anyone has ever known.
