Clyde Langer

Clyde Langer was a classmate of Maria Jackson and Luke Smith at Park Vale Comprehensive School who joined them on adventures with Sarah Jane Smith involving aliens.

Biography
Clyde's father, Paul had walked out on him and his mother at an early age, and went off with his mother's sister. (SJA: Warriors of Kudlak, The Mark of the Berserker)

At around age 14, Clyde first met Maria and Luke on his first day at Park Vale School. He considered himself one of the "cool kids". Clyde had a rebellious streak and 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 was 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. In the aftermath of this, Clyde decided to join the others in fighting evil aliens and to tutor Luke in the ways of "coolness". In contrast to the others (and to previous casts), Clyde showed no moral qualms about the Slitheen being killed - "They were going to kill billions of people, I dunno what the big dillema was". (SJA: Revenge of the Slitheen)

His grandmother, who knew Mrs. Randall who lived at Lavender Lawns, tipped him off that there was something strange happening there. The claims she made were in fact true as the manager, Mrs. Gribbins, was in league with a Gorgon. (SJA: Eye of the Gorgon) He and Luke went to laser tag centre where he and Luke were teleported to General Kudlak's battle station. There he met others kids who had gone missing due to winning a Combat 3000 game. He was helped to get home safely with the help of Sarah Jane. (SJA: Warriors of Kudlak)

He was with his mother during the events of Earth's transportation to the Medusa Cascade and its subsequent invasion by the Daleks. (DW: The Stolen Earth)

Though he kept the talent secret, Clyde had a talent for drawing and cooking. (SJA: The Mark of the Berserker) He is good at throwing an object to a targert, which maybe shows he's good at sports. (SJA: From Raxacoricofallapatorius With Love)

Habits and quirks
