Subspace was previously coworkers with Medkit. He is now sworn enemies with Subspace, even when they worked with each other, they never liked each other.

He cannot handle spicy food.

Medkit can be seen as outwardly forlorn, being cynical and sardonic at the expense of others but also caring about them as a doctor would. Despite this, Medkit despises being a doctor, yet was ironically created with the gift of healing. He is more fascinated by technology and engineering.
