Well thanks to all for your opinions on Malibu's colour schemes. Some interesting ideas there but for the moment I'll use this here green.

Stealth Malibu is, to me, the fourth type of comic secret agent.
Austin Powers is good and he knows it.
Frank Drebin is bad but thinks he's good.
Johnny English is bad and he knows it.
Stealth Malibu is good but thinks he's bad.

You could probably argue these opinions but the point is that Agent Malibu's outlandish claims and ill conceived actions usually end up working, but only when nobody's really looking so everybody, Malibu included, believes he's just messed something else up. Not too easy to explain but I have come up with a few specific jokes that I think explain it better.

His "gimmick" is that, despite being a secret agent he's not always that secret about it. This can be seen in the clear divide between secret and obvious in his name, clothing and car.

Stealth Malibu Disasters:

LEVEL 1: Silent Objective: Malibu whips out his SUPER SILENCER and attaches it to his gun before firing a shot at his opponent (which will momentarily stun them) but the effectiveness of the silencer is apparent when it makes no sound whatsoever. At this point, Stealth believes it to not be working and bangs on the gun several times, unaware that with each strike another shot is being fired, before eventually tossing the silencer away in dismissal.

LEVEL 2: Toothfaker: More gadgets this time as Agent Malibu presents...a toothbrush. As he puts his head in his hand in disappointment the toothbrush transforms into a heavy duty laser which fires a powerful beam before Stealth looks up again and tosses the toothbrush away.

LEVEL 3: ?????
