He's a enigmatic individual who serves as the 'Toads' mentor, being affectionately referred by them as "Coach". He is known to have an enormous intelligence...and for being viciously unforgiving to the 'Toads when they fail their IMPOSSIBLY tough missions which either means he's really as tough as he says...or he's just a REALLY big jerk. Either way, the fact he's cheering for their victories and remorseful for their failures shows he DOES truly care through his tough love.
