Connor

Connor is an officer or NCO considered to be greatest of all knights of The Forever Knights.

He was assigned by Patrick to slay an Alien Dragon that the Forever Knights have kept imprisoned. After it escaped, Kevin ended up having Ben and Connor work together to catch it. When Ben learns the truth about the Alien Dragon, he covinces Gwen and Kevin into keeping Connor from slaying it.

After the Alien Dragon escapes back to its 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 alien world out there containing Alien Dragons.

He 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.

The last time he was seen it was apparent that he was going to get revenge on Ben, Gwen, and Kevin.

It is unknown if he will appear in Ben 10: Ultimate Alien, though it is very likely. It is possibly that he and King Urian are related.
