name-seikatsu (his name means life)

sex-male

he is the son of shredder, unlike karai who is the daughter of splinter.

unlike karai who is loyal to her father,seika only acts like he is to his but seika only wants to take his fathers place and become the shredder himself.

he has tried to take his fathers life more than once just not by himself he has paid many to do the job for him but have failed.

he and karai fight for their fathers trust and try and show who could be the future shredder,he did tell them if he ever died the one he gives his mask to shall be the next shredder.

seika doesn't care much about his sister or father he is very cruel,the reason why is beacouse shredder treated karai like family and seika knows karai is not his sister.shredder was abouseve to seika and would hurt him if he did the smallest thing wrong and shredder made him call him master instead of father.

from all the pain,it turned his soul from full of hope and warmth to hate and cold

sakias armor and weapon-

he has met the ninja turtles before and other mutants,but never cared for them.

when seika is out in public he is a very nice and calm man but when he is doing his work he is mean and nasty.

the thing is all sekia wanted was a fathers love and what it felt like to have one who would call him his son,he wanted to make his father proud and make him smile but karai took it all from him and he never got the care or love he wanted...

btw him as a mutant-

he can turn to his human form and back but his eyes stay black and red.

his spikes on his back and tail have bits of acid to if he wants he can shoot out his spikes and they can burn through somone.he has very sharp teeth 

he blames this on karai,karai meant to push him out the way of a gun about to kill him but he fell into a pool of mutagen (idk how to spell) nearby and it had the DNA of a turtle and snake turning him into...i guess a snurtle?

(btw he is not like this in the beginning of rps but could or will in rps turn into this)

(also he still has his big eyebrows XD)
