Alistair only appears in Chapter IV and his name can be entirely missed if the player rushes. He uses a generic character model and voice and cannot be distinguished from other barbarians.
Keenan and Alistair are among the first 3 barbarians encountered in the chapter, the third appears to be an officer and barks orders at them. After the officer gives them their orders and asks if they have any questions, Keenan sarcastically responds "What time is it?" at which point the officer calls him by name "Shut your mouth Keenan!" and then tells him to go set traps and guard the paths. He then calls Alistair by name when he says "Alistair, you stay her with me".
Keenan and Alistair can both be killed on this initial encounter if the player immediately jumps down from the ledge and initiates a fight with them. If not, Keenan leaves to go carry out his orders and can survive the chapter, but Alistair must be killed in order to proceed.
- The name Alistair is of Scottish origin. While many barbarians encountered throughout the game appear to have Scottish accents, Alistair is the only distinguishable character other than Glott and possibly the Oracle who is explicitly identified as Scottish.
- Coincidentally, his counterpart Keenan is the only character in the game who is of known Irish descent. In addition, in a conversation between another group of barbarians in the same chapter, a Brit loudly barks "You got picked for forest duty because you're a Scot" so it is likely that Both Alistair and Keenan are treated as subordinates simply because they are foreign.
