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). After this threat was pasted the world was returned to normal (DW: Journey's End).

He helped Sarah Jane in subsequent adventures such as against the Sontaran Commander Kargh. Shortly afterwards, Rani Chandra, an aspiring teenage journalist, and her parents Gita and Haresh moved in to Maria's former address and joined Luke and Clyde in defeating a child-stealing energy entity which had inspired the Pied Piper myth. Reluctantly, she took Rani into the team. The entity thrived off of Sarah's fears of clowns which started one night in childhood. (SJA: The Day of the Clown) Afterwards, Rani joined the team permanently. Together, they defeated the Ancient Lights (SJA: Secrets of the Stars), the Berserker (SJA: The Mark of the Berserker) and even the Trickster when he attempted to manifest corporeally in Foxgrove in 1951. (SJA: The Temptation of Sarah Jane Smith) Later, Mrs Wormwood returned to Earth alongside the Sontaran Kaagh in an attempt to summon Horath, the immortal tyrant of the Dark Empire. With help from Brigadier Lethbridge-Stewart, and due to infighting between Kaagh and Mrs Wormwood, they were able to stop this potential apocalypse. (SJA: Enemy of the Bane).

He later helped defeat Androvax and stop him from destroying Earth with Nanoforms. (SJA: Prisoner of the Judoon).

When Sarah Jane announced her wedding to Peter Dalton, he thought she was rushing and was determined to find a flaw in Peter. He is teleported along with Luke, Rani and the Doctor who crashed the wedding to nowhere in a time trap. Thanks to the TARDIS' power he was able to hurt the Trickster to the point of exhaustion aswell as Peter withdrawing the Trickster's agreement, they are able to escape and the Trickster explodes into nothing. He gets a look inside the TARDIS when the Doctor comes to Bannerman Road. (SJA: The Wedding of Sarah Jane Smith)

(SJA: From Raxacoricofallapatorius With Love). He briefly obtained the power of the TARDIS that he was able to use to hurt the Trickster The Wedding of Sarah Jane Smith.
