shes_intense : Brenda's sn comes from a classic conversation she had with Paco early in the Blue Beetle series where Paco told her she was a very angry girl and she told him 'I'm not angry, I'm 'intense'. She then pointed out that 'intense' was the kind of wording that went on a college application and Paco retorted that no, it was the kind of wording that went in an angry woman's personal ad. XD

wantstobebatman : Batman is Doc McNinja's idol. He has Batman PJ's, and asks himself 'what would Batman do' in tough situations. He has also been outrightly accused of being 'a doctor who wants to be Batman' in his canon so... yeah. It just fit.
