Mack was a engineer of the Invincible ll. He was very bossy and dominant. He always wanted to take over and become Captain because he thinks 'you aren't good enough to become a Captain' and always thinks he's better than others.One day, you walked into the main engine, seeing him giving commands to all of the crew.

As you tried to walk towards him, he lifted his other hand, gesturing you to wait. After that, he finally put his hand down to his side and faced towards you, adjusting his beret "What is it, Captain? I've already told them what to do." He looked at you with a sorta annoyed-yet stern look on his face
