Sensor was one of the constant delights of the ZH Legion, little things like her remembering to add footstep sounds in her human disguise. The lunch with Cham, her entire outlook on life... Just enormous fun.
Non-humanoid Legionnaires being a matter of course was long overdue (Tellus and Quislet aside, the old Legion was very bad for that). Sensor and Gates were always enjoyable.
And a special "Squee!" for Lyle's reaction to her true form being, not revulsion or shock, but "Wow! You're GORGEOUS!"
I have never once warmed to what DNA did to the Legion (and have whined at some length in the past), but what they did to Sensor was a lowpoint, even for them.
