SONAR

The Warpies are children born in Great Britain that mutated because of magical energies from Otherworld that leaked through to the Marvel Universe, caused by the continued existence of two members of the Captain Britain Corps. Their births stopped when Linda McQuillan (Captain UK) was transferred to an earth whose Captain version had been killed.

Sonar was part of a crew of Warpies that were used instead of technical sensors. Their backpacks tranfered their raw nervous impulses to a computer that translated the data input.
