S.H.I.E.L.D.

Sam and Max

Sam and Max are a dog and a lagomorph that fight crime and have fun, I guess. Check out Steve Purcell's comics and the adventure games!
Improbable Mission

This clip will explain it all.
Dr. McNinja

Dr. McNinja is a doctor who is a ninja. Go read the webcomic!
Elite Beat Agents / Ouendan

Well, they don't help people directly, but they sure can dance!
