So I was reading your ranking exam and now I have to tell you about yourself. You remind me of a cheap ass Hiro Mitarashi. Because I control a certain energy that is the conduit for all energies I can manipulate the potential energy of anything and make it stop! Shenanigans...
Now, before Zorro strikes your jutsu list with his bad ass seal of approval Im going to need you to consider a couple things because you are obviously not aware of them.
There is a certain energy hierarchy, when a genin attempts to stop a wave of natural energy the genin should get owned and die upon attempt. Why? Because the chakra consumption to stop said wave would be WAY to immense to even consider the feat. You preformed such a task like you stop waves of natural energy for breakfast! Wrong... Natural energy is Sannin worthy powers... and it should take, Jounin-Kage strength to stop such powers. Your Caesarea craps should require an awful lot of chakra consumption. Stopping potential energy is a grand feat in itself... food for thought
Now... converting peoples energy substances, there are some things on this site that you just can not manipulate. Lets take... I dunno... makai chakra for example.
If zeik fired a blast of execution at you, you stop the blast by infecting it with Caesarea energy. Makai infects whatever is applied to it so it would be a clash
Lets take the P.C now...
I fire a gaia cannon at you...
you attempt to stop it by infecting it wtih Caesarea energy... my P.C destroys anyting and everything it touches that is matter. Take the specific affects of peoples shit into account before converting their shit. Your energy is still energy and must deal with the special affects of everyon elses shit as well before converting it.
fell free to correct me if i am completely wrong, but youare WAY to cheap. this is ninja... you will be limited accordingly.
