It's not unheard of for original characters coming from actual unpublished fiction to unexpectedly drop in the PPC and hang around-- Agent Miah Arthur is an example of this. Besides, a plothole dragging an OC into HQ doesn't need to be explained: that is the very nature of plotholes themselves.
The SNK agent sounds cool, but I'd recommend to drop the shifter idea if she's going to kill badfic. That's getting dangerously close to Speshul, because it's both a rare power (we still don't understand how Shifters work) and a complete game breaker for PPC missions. Besides, where are you going to use those powers? Most 'verses don't have people randomly shift into Titans.
Or you could have her go into External Security... Things get pretty hairy when defending HQ from extradimensional threats, so I'd love to see how that plays out...
Another great tool you can use to help guide yourself is Huinesoron's Permission Self-Check. It's useful for asking yourself the right questions when designing an agent. No need to submit your answers at the very end of the exercise.
