Answer:
Lone wolf.
Step-by-step explanation:
A lone wolf is someone that works and exists independently rather than with others as a member of a team. Is typically introverted, self-motivated, and is extremely focused on completing her/his own tasks.They have a strong preference for independence and doing most things on their own. Loners or “hermits” have a reputation of being biased. As a rule, they are not entrusted with large, profitable projects. At least not often.
By contrast, the latter case is a team player who needs the interaction of others to assist their own personal performance.
