He was Sasuke up to a T, also done back when I was a freshman so it had lots of edge>Pale, raven black hair, fiery look>Big brother kills parents and almost kills him (left him for dead) to get powers from a demon pact>Character decides to take revenge and get powerful no matter the costs to kill said brother>Monk with feats that allow him to use flurry of blows with longsword (refluffed katana)
Started as LE, took a while for the Gm to let me play it becase, well LE, but I kinda struck a deal with the party. I was "hired", and because money interested me I made a contract with them.
With time I kinda grew acostumed to the other PCs and even found them enjoyable.
With more games I as a player even forgot about the revenge from time to time (and so I did the same for the PC), having friends, going on adventures, saving people slowly changed my char to LN
Then an almost TPK happened because I fucked up, not on purpose, I got caught by the lieutenants of an evil mercenary group with lots of contacts continent wise and powerful people (that we had been fucking with).
They used me as hostage to get the mcguffin, they didn't hold the part of their deal and attacked my comrades. Combat was brutal and I felt powerless because 1. I couldn't untie myself on time, 2. failed 90% of my attacks, and no it isn't an hyperbole, enemies literally ignored me and ganged up on the other three PCs, 3. two PCs died in front of me, thrid had to withdraw and 4. the only bad guy standing cast invisibility on himself and withdraw laughing through a corridor I followed him (easy because corridor) because good perception but couldn't hit him because 50% chance so he laughed even more and by the time we reached an open field I couldn't follow him anymore.
Then when I found news about my evil brother I decided to ignore them and continue my journey with the other party member to find a way to bring our friends back. Game ended a couple of levels later but by then I was LG.
