Slingshot

TO ELENA'S REQUESTER AND OTHER PEOPLE THAT MAY BE INTERESTED IN FINDING OUT ABOUT HER: Slingshot or Yo-yo moves at least as fast as 40 miles in less than a minute. So, 40/1 × 60/1 =2,400 mph or at least faster than that. The speed of sound is 761 mph. The speed of sound is the rate a sound reaches a target after it is erected from a source. She is at least more than 120 mph faster than mach 3 and could be way faster than that(depending on how much faster than a minute she ran 40 miles). Then, she Yo-Yoes back to the point she came from(possibly out of danger if she falls or is vulnerable after stopping her run). This means she has very good to borderline great speed and you have only one shot to hit her. For reference, search writeups and Marvel's page* on her character...

*I was surprised at how much info Marvel had on her. They are usually very classified on their characters. I think that's a flaw when a comic book company does that, but that's just me. It seems as though not knowing the character specifics could lessen your stock over time, but that's just me...Funny, how they turned into Milestone(a company they themselves bought--only to be bought off themselves). But, they have good info on Slingshot, though...
