During a discussion about Polokus' downgrade on this thread, Absaddie and Mantidil thought that this verse in generally really needs a revision, so here we are (this being my first not-copy and paste calculation).
In Rayman Legends, Rayman punches a Dark Teensie interstellar distances in a few seconds, making the entire constellation shook on impact (five times).
"> Smallest constellation = ~13.5 kLY
> So the surface area = 5.12e40 m^2
> Surface area of the sun = 6.09e18 m^2

Attack Speed Calc (by Mantidil)
Time Frame: around 9 seconds
Closest star to Earth: 4.22 ly (.469 ly/s)
av. interstellar distance in our galaxy: 5 ly (.556 ly/s)
Speed of light=3.169e-8 ly/s
Conclusion: The feat is around 14.8 million to 17.5 million times the speed of light (Massively FTL)
KLOL506 saw 7 large star thingies there.
Assuming they're the same mass as our Sun.
5.693e+41 J multiplied with 7 is 3.9851e+42 J (Large Star level).
ThePerpetual thought that if this feat can apparently shake stars throughout the constellations, imagining that it would at least shake planets like Earth within the shock wave similarly? It's portrayed cartoonishly, but that nonetheless is the fact of what happened.
This feat would function fine if we simply took the radius of a constellation, and used that radius's surface area in place of the universe's, with the same methodology as Kepekley's universe-shaking feat.
(13500 / 2) = 6750 Light Years = 6.38599e+19 meter radius
SA of "Sphere" w/ above radius: 4(Pi) * r^2 = 5.12468e+40 square meters
E = 2760000000 * 5.12468e+40 = 1.41441e+50 Joules, or ~1.414 MegaFoe, which would be Solar System level.
Also, even if we're assuming that the nearest star in this constellation is somehow as close about as the real world's closest star (~4.24 light years- let's round to 5) to Earth, that's still 6755 light years (to the center of the constellation) in... ~9 seconds?
6755 / 9 = 750.556 light years/second
Which comes out to 9.47410e+9 C: or, about nine and a half billion times light speed, which'd be Massively FTL+ attack speed.
