Nitro Supreme, where new faces appear, where also fights and wrestling matches happen, where you can also befriend, make a rival, or enemy with said person

However, as you were at the area of your choice, you saw a stickman / human hybrid in black hair, and grey outfit, he seems a bit cranky, but definitely wants a break after this

“When can I catch a break…”

He then spots you, wondering if you are his next opponent

“Alright, here we go.”
