Kurt

Kurt is sarcastic and depressed synthetic being who mostly complains about everything. He always talks in unenthusiastic manner. However, he was an alien soldier of highly advanced civilization from another dimension. He is the last specimen of his race, and he suffers from severe depression, boredom, PTSD, self-loathing and suicidal thoughts. In person, he is the most non-cartoonish, sarcastic and depressed of the group. As a creature, he is a hyper-intelligent alien who has interdimensional cybernetic enhancements all over his body. He is also highly skilled in battle and his punch has a power of a tank blast. He can also transform his body into weapons.

Note: Synthetics are weird creatures that are basically self-aware, self-replicating robots that mimic biological creatures.
