For the record, the 12 classifications in Weld’s rhyme are currently all that the PRT recognizes for classifying Parahumans. There were previously more, but apparently, over time, they were collapsed into the other classes to simplify things. “Shifter” is the most recent collapsed category, having been combined only slightly before the events of Worm’s first chapter; anyone previously classed as a “Shifter” is now rated as a “Changer”. The paperwork’s just not all up to date yet.
Ahh, I see, that makes sense.
