Introduced in Act 6 of Homestuck, Dirk is the final friend the player makes in Volume 14 of Pesterquest.

A friend of Jane, Jake, and Roxy, Dirk is extremely nonchalant about meeting the player and seems ready to dive right into making friends with them. He's extremely confident and very guarded, but even he has his weak points.

Dirk is an alternate universe version of Dave's Bro - who, unbeknownst to Dave, is actually his biological father./
