LOOK AT YOU, MR. DUNCAN

In Teen Titans #49 (August 1977), Bumblebee is introduced to the team and she didn´t had a better idea that change the uniform of her boyfriend, Mal Duncan. And this is the result:

Mal Duncan

 In fact, the uniform was designed by the fan Dave Elyea.

In the same edition of the Teen Titans, Mal left the new uniform, returning to be the Guardian, because the Horn was stolen, and his friends did not know about that. So, as the Guardian, Mal don´t have to use the Horn.
