Ollie

Someone who is good at everything without even trying. Also likes to take big risks. Can be a bit bossy and a high-maintenance pusher, but only because they want the best for everybody.

"We lost the match! How are we gonna win?"
"Let's call Ollie in!"
"But he's a bit bossy sometimes-"
"And we need him. He means well. Also he's pretty chill once you get to know him."
~later~
"Wow Ollie carried all of us!"
"See? I told ya he's awesome!"
