Scottie

Scottie is a blink dog who serves as the party's mascot. He has an unusual talent for occasionally blinking to other planes. Despite his name, he looks (and acts) like a Golden Retriever.

Who's a good boy?
Scottie is.

Who's a helpful boy?
In addition to occasionally blinking in with interesting treats from very far afield (including one of the Lanterns), Scottie is a natural at working the transporters on The Afterthought for tactical insertion and extraction of the party. He also scares the bejeezus out of Xenia.

History
The party won local fame by breaking up a blink dog fighting ring which used a combination of walls of force and rage effects for bloodsport. While the other blink dogs ran away to rejoin their society, Scottie chose to remain behind and accompany the party.
