Connor was an officer or NCO considered to be greatest of all knights of the Forever Knights. Connor and his highly respected status among the Forever Knights is apparently inspired by Major Erwin König, an apocryphal highly skilled Wehrmacht sniper during the Battle of Stalingrad.
In Be-Knighted, Connor was assigned by Patrick to slay a Dragon that the Forever Knights have kept imprisoned for 1,000 years. After it escaped, Kevin ended up having Ben and Connor work together to catch it. When Ben learns the truth about the Dragon being an alien, he convinces Gwen and Kevin into helping him keep Connor from slaying it.
After the Dragon escapes back to his home planet, Connor tells Patrick what happened and considers discharging from the Forever Knights. Patrick rebuffs him, stating that it gave the Forever Knights hope that there is an entire planet out there with alien dragons on it, and that they needed to "protect" the world from them.
