Jim Kolb

Jim Kolb is a recurring character in The Powerpuff Girls, one of the Devon Group's leading four members and John Utonium's former head scientist.

Before Season 2
Kolb joined the Devon Group shortly after Mr. Devon recruited John Utonium. Kolb was Utonium's college roommate and the only person Utonium even remotely considered to be even closely as intelligent as he was, even though he was studying business. Kolb and Utonium never got along, and Kolb was pleased when Utonium left with Kathleen Keane and was promoted to leading member.

Season 2
Kolb arrived in Townsville shortly after Ryan Parker warned Utonium that the Devon Group would soon be coming. However, Kolb met Tyler Osborn at his home. Osborn demanded to know who he was, and Kolb introduced himself while offering to exchange information about Utonium's past in exchange for access to the Powerpuff Girls. Osborn assented to this deal.
