Matrix took on the role of support because cares for people a lot. During his time on the run, Matrix found lots of people starving and homeless. Whenever he saw them, he would always give them food rations or bits of money he had to them. This kept on going to the point where Matrix would sometimes even go broke because he gave out to much. Matrix would much rather sacrifice himself then let someone else get hurt. This is because he knows that he could've helped them so he couldn't stand the guilt. He started acting this way since one time, Matrix witnessed a little child getting beat up by these older people. Seeing this sight, Matrix stood there, frozen, unknowing what to do. He stood there, watching the kid get beat up, not doing anything. He is still haunted by the thought that he could've saved that kid. Now in the realm of Shatterspace, Matrix tries to do anything he can to make someone just a bit happier by doing things like showing them magic tricks or just having a talk with them. Matrix didn't have much friends back in the real world, so he's always trying to make friends with the people in the Shatterspace realm.
