Clyde Langer
Clyde Langer was a class mate of Maria Jackson and Luke Smith. He met Maria and Luke on his first day of high school. He disliked the school dinners as the food was rotten due to a Slitheen machine in the school. The next day he brought a home made chip sandwich to school where the science teacher, a Slitheen in disguise, had a negative reaction to the vinegar in the sandwich as vinegar is the Raxacoricofallapatorian's weakness. After school his science teacher unmasked and chased Maria and Clyde, Clyde sprayed deodorant to confuse the advanced sense of smell of the Raxacoricofallapatorian. After meeting Sarah Jane Smith he helped defeat the Slitheen. (SJA: Revenge of the Slitheen)
