Use any kind of any logic, the definition of words/names and determine what kind of powers & looks you get based on your the Questionable Questing username.
My name has quite the backstory...
It comes from a character from one of my stories in a lot of ways, but I think I can safely ignore the whole Mass Infection of Revenant Artificial Intelligences part since that's just how I name characters. The name proper refers to her signature attack in the Japanese version of the story 未来衝撃波(みらいしょうげきは)or "Miraishougekiha." Translated literally, that means "Future Shock Wave." So, taking that into account...
Well, 4-dimensional sonic booms, basically. When you break the sound barrier, a shock wave is created. In this case, it revolves around the acceleration of
something to the speed of light or some trash and causing a detonation in space-time. In the same way a sonic boom can cause widespread devastation via the mass release of force and heat, this would basically ravage the timelines and—as its name—all future branches off that particular timeline. In the story, the people fighting MIRAIs are unknown to history because the sheer amount of localized damage this attack did to the World Line makes it impossible to get a clear picture, even for superbeings and their omniscient perks.
What does that mean for me? Not a damn clue because even if I make that the power off the name alone, there's the whole fact that the attack isn't just the shattering of our beloved universal constant, it's the directed energy blast that follows it. Given that this 4D attack is already causality-raping in principle, it also takes that massive energy release, then funnels it toward a chosen target. In that sense, I guess the power is more a rail gun or heat ray taken to the absolute extreme. I'll settle for that, though.
The key principle of this whole technique is that it kinda works like quantum tunnelling. Yes, there is a directed heat blast, but this is done at the expense of causality. Whatever "future" was that was accelerated, it will be paid back once causality re-asserts itself. So, uhm, that kinda means that even if you dodge the attack, it's possible you'll be killed off once the temporal sonic boom strikes and things start imploding due to having been yoinked back in time to become an ungodly energy blast. It doesn't really have to be objects, though. Since we're talking about seemingly infinite energy, even a proton's mass being borrowed packs a serious punch.
The good news? I can probably rape the the 4th and 5th Dimension and thus probably have a 6th Dimensional power to comprehend and contain the energy flux. If I don't have at least 6D perception or power plus absurd durability to go along with it, I'd probably die immediately if I ever tried to use the power. At the same time, from a writing standpoint, the hero having a power that she'd die if she ever used has its own narrative appeal to me.
Having said all that, take note that I'm using higher physics definitions of "dimension" where the 4th Dimension is time, the 5th Dimension is the potential for alternate World Lines caused by choice and chance, and the 6th Dimension is a vector by which one can move between two separate World Lines.
Then tell us who you can do in the real world and look like.
Who I can do in the real world and look like? Eh... Well, that's worded weirdly, but I doubt my appearance would change. Smol girl with overblown "Future Shock" power, go!
If you got numbers then they will boost up the stats of strength/speed/etc like a dragon ball z character's transformation. could you beat me and anyone else from Questionable Questing with their username's powers?
I'd not like to judge this myself. If you feel like reading my post, feel free to decide if you could beat my power. Given how durable I'd be if I could use the power multiple times, I'd suggest packing some serious (and literal) heat. Have fun with the power scaling clusterfuck that comes with that nonsense.
Bonus event. Adult Franklin Richards sent you with username powers into Marvel's 616 earth.
I'll admit to not knowing anything about Marvel, but a cursory search makes me wonder how I'd handle being in a world of superheroes and supervillains. There's a lot of debate how that will go, though. First off, since the power I have, by definition, affects the future and branching futures of the timeline where it is used, I might very well end up being labeled a villain since using my power would cause permanent damage. Sure, it'll just be a heat blast at first, but as time goes on, the actual damage done will manifest as time catches up with the super-relativistic calamity. With that in mind, I'll leave it to the comic book experts to figure out what that means.
Kirby's copying event.
Kirby eats your username. What powers does he get?
For example, with my username, he becomes a sailor scout with magical pizza powers.
could he still beat up any villain from his series to eat some cake or whatever?
Same power, I guess. He becomes Mirai Kirby with the power to deliver super-powered heat rays that hit people several seconds in the future. Definitely gonna be able to beat up the villains, eat some cake, and then maaaaybe notice that time seems to be distorted for a while.
