While at the Plumbers' Academy, Lotin wears the standard Magister uniform. Upon leaving the Academy to become a full fledged villain in Detention, he keeps the same basic appearance but the colors change from the green and black of the Plumbers' Academy to the red and silver of the Villain's Academy.
After making his return following his disappearance in early summer 2014, he ditches the Academy-esque appearance completely, in favor of black body armor. At some points, he is also seen wearing black and dark purple robes.
When he is seen in prison in the second season, he wears standard prison gear, along with all the other prisoners.
