Since Lilo and Stitch is in style again, Why not Disney-fy my fursona and turn myself into an experiment? I've been a fan of the movie and TV show as a kid and real big shame they never featured all 627 experiments. If I do turn this into a YCH, there's 500+ numbered slots available.

"Experiment 621 activated. Primary function: kinetikinesis and energy conversion"
*reading in Jumbaa's Russian accent*
"Ahhhhhh! Experiment 621 (AKA "Snapback")! Definitely one of evil genius' favorite experiments... and most dangerous! Ah ha! I have never been more proud of any experiment I ever created in whole evil genius career... other than you, 626 of course! He never fails to disappoint in wreaking havoc everywhere! Ah ha ha! He is is able to absorb, store, and release energy all at once or in smaller packets (think Sebastian Shaw from X Men First Class and the comics but far more dangerous). 621 is capable of completely bringing the fastest intergalactic cruiser at hyperthrust speeds to a sudden halt and harnessing the energy from the motion of the vehicle. In addition to being able to manipulate thermal, electrical, light, kinetic, and atomic energies, he is capable of converting one form of energy to another. A fiery explosion can be released as a deadly punch. Contact made with moving vessel can be harnessed to give himself a thrust. Don't be surprised to see himself turn into a rocketing jet as he launches himself with his elastic legs. Ah yes, about that. Like 345, 621 has elastic limbs at the neck, wrist, and lower legs as indicated by the red arrow markings at wrist and ankles. Ah yes, you want to know weakness? Like you, 626 he is indestructible. However, he does have limits to how much energy he may absorb. He can absorb.... eh... conversion, ah yes, about equivalent to human unit of 300 megatons of TNT. The amount of energy he can store is indicated by the length of the 5 spines on his back. The more energy, the more spines protrude and the greater the length. After reaching limit, he begins to succumb to whatever energy he is exposed to. So, only try to defeat him when his spines are nearly all retracted. Also, I am sure you will find great difficulty in trying to punch water or sand, yes? How well do you think 621 will do being trapped in some thick fluid? One more thing! 621 has a cocky, showboater personality. He is very proud, never backs down from a challenge. Perhaps you can trick him into using up his energy reserves when in combat?"
