<P> Many of the main character's relatives appear throughout the show, such as Lily's father or Barney's brother . They may also be seen in family gatherings, such as Barney and Robin's wedding or Marshall's father's funeral . Ted's children and Marvin W. Eriksen (son of Marshall and Lily) appear in the background of many episodes without being crucial to many plots . </P> <P> Ranjit, Carl the Bartender, and several other characters often appear because they work in places the main cast frequent (such as MacLaren's Pub). Characters in relationships with Ted, Barney, or Robin often appear in several episodes within a short period of time, such as Victoria, Nora, or Kevin . Minor characters such as the Slutty Pumpkin or Mary the Paralegal may only appear in one or two episodes, but still play a crucial role in the episodes in which they appear . </P> <Table> <Tr> <Th> Season </Th> <Th> S1 </Th> <Th> S2 </Th> <Th> S3 </Th> <Th> S4 </Th> <Th> S5 </Th> <Th> S6 </Th> <Th> S7 </Th> <Th> S8 </Th> <Th> S9 </Th> </Tr> <Tr> <Th> Character </Th> <Th_colspan="9"> Main Characters </Th> </Tr> <Tr> <Th> Ted Mosby </Th> <Td_colspan="9"> Josh Radnor </Td> </Tr> <Tr> <Th> Robin Scherbatsky </Th> <Td_colspan="9"> Cobie Smulders </Td> </Tr> <Tr> <Th> Barney Stinson </Th> <Td_colspan="9"> Neil Patrick Harris </Td> </Tr> <Tr> <Th> Lily Aldrin </Th> <Td_colspan="9"> Alyson Hannigan </Td> </Tr> <Tr> <Th> Marshall Eriksen </Th> <Td_colspan="9"> Jason Segel </Td> </Tr> <Tr> <Th> Tracy McConnell </Th> <Td_colspan="7"> </Td> <Td_colspan="2"> Cristin Milioti </Td> </Tr> <Tr> <Th> Future Ted </Th> <Td_colspan="9"> Bob Saget (voice, credited) </Td> </Tr> <Tr> <Th> Character </Th> <Th_colspan="9"> Secondary characters </Th> </Tr> <Tr> <Th> Arthur Hobbs </Th> <Td_colspan="2"> </Td> <Td> Bob Odenkirk </Td> <Td> </Td> <Td_colspan="2"> Bob Odenkirk </Td> <Td> </Td> <Td> Bob Odenkirk </Td> <Td> </Td> </Tr> <Tr> <Th> Becky </Th> <Td_colspan="5"> </Td> <Td> Laura Bell Bundy </Td> <Td> </Td> <Td_colspan="2"> Laura Bell Bundy </Td> </Tr> <Tr> <Th> Bilson </Th> <Td> Bryan Callen </Td> <Td> </Td> <Td_colspan="2"> Bryan Callen </Td> <Td_colspan="5"> </Td> </Tr> <Tr> <Th> Brad Morris </Th> <Td> </Td> <Td> Joe Manganiello </Td> <Td_colspan="2"> </Td> <Td> Joe Manganiello </Td> <Td_colspan="2"> </Td> <Td> Joe Manganiello </Td> <Td> </Td> </Tr> <Tr> <Th> The Captain </Th> <Td_colspan="5"> </Td> <Td> Kyle MacLachlan </Td> <Td> </Td> <Td_colspan="2"> Kyle MacLachlan </Td> </Tr> <Tr> <Th> Carl MacLaren </Th> <Td_colspan="2"> Joe Nieves </Td> <Td> </Td> <Td_colspan="6"> Joe Nieves </Td> </Tr> <Tr> <Th> Claudia Bowers </Th> <Td> Virginia Williams </Td> <Td_colspan="2"> </Td> <Td> Virginia Williams </Td> <Td> </Td> <Td> Virginia Williams </Td> <Td_colspan="2"> </Td> <Td> Virginia Williams </Td> </Tr> <Tr> <Th> Curtis </Th> <Td_colspan="8"> </Td> <Td> Roger Bart </Td> </Tr> <Tr> <Th> Daphne </Th> <Td_colspan="8"> </Td> <Td> Sherri Shepherd </Td> </Tr> <Tr> <Th> Don Frank </Th> <Td_colspan="4"> </Td> <Td> Benjamin Koldyke </Td> <Td_colspan="4"> </Td> </Tr> <Tr> <Th> Doug Martin </Th> <Td> Will Sasso </Td> <Td> </Td> <Td_colspan="2"> Will Sasso </Td> <Td_colspan="2"> </Td> <Td> Will Sasso </Td> <Td_colspan="2"> </Td> </Tr> <Tr> <Th> Gary Blauman </Th> <Td> Taran Killam </Td> <Td> </Td> <Td_colspan="3"> Taran Killam </Td> <Td_colspan="3"> </Td> <Td> Taran Killam </Td> </Tr> <Tr> <Th> James Stinson </Th> <Td> </Td> <Td_colspan="2"> Wayne Brady </Td> <Td_colspan="2"> </Td> <Td_colspan="2"> Wayne Brady </Td> <Td> </Td> <Td> Wayne Brady </Td> </Tr> <Tr> <Th> Jeanette Peterson </Th> <Td_colspan="7"> </Td> <Td_colspan="2"> Abby Elliott </Td> </Tr> <Tr> <Th> Judy Eriksen </Th> <Td> Suzie Plakson </Td> <Td_colspan="3"> </Td> <Td_colspan="2"> Suzie Plakson </Td> <Td> </Td> <Td_colspan="2"> Suzie Plakson </Td> </Tr> <Tr> <Th> Kevin Venkataraghavan </Th> <Td_colspan="6"> </Td> <Td> Kal Penn </Td> <Td> </Td> <Td> Kal Penn </Td> </Tr> <Tr> <Th> Linus </Th> <Td_colspan="8"> </Td> <Td> Robert Belushi </Td> </Tr> <Tr> <Th> Loretta Stinson </Th> <Td> </Td> <Td> Megan Mullally </Td> <Td> </Td> <Td> Frances Conroy </Td> <Td> </Td> <Td_colspan="4"> Frances Conroy </Td> </Tr> <Tr> <Th> Lucy Zinman </Th> <Td_colspan="2"> </Td> <Td_colspan="2"> Darcy Rose Byrnes </Td> <Td_colspan="5"> </Td> </Tr> <Tr> <Th> Luke Mosby </Th> <Td_colspan="9"> David Henrie </Td> </Tr> <Tr> <Th> Marcus Eriksen </Th> <Td_colspan="2"> Ned Rolsma </Td> <Td> </Td> <Td_colspan="6"> Ned Rolsma Gibson Sjobek (young) </Td> </Tr> <Tr> <Th> Marvin W.
