A brilliant strategist, Stalker prefers to take things slowly and carefully. Though a snail didn't seem like the best beast mode to take on, his impenetrable shell would allow him to sit in the middle of the most violent battles and plan his next move carefully.
This is what he expected at least. Infested with parasites that his stasis pod could not discern from the beast that it scanned, the Predacon is now at their mercy. The once great strategist can now only offer battleplans that involve standing out in the open for long periods of time. This has led to his demotion to ship's cook until Megatron can find something better to do with him.
