- For the E-Series robot, see E-04 Leon.
Leon and the rest of his team, betrayed Molly and made a pact with the Metarex with the promise that if they were to deliver Doctor Eggman to Pale Bay Leaf, then the Metarex allow them to join them, so they could be spared. Knowing that she wouldn't go along with his plan, Leon asked Molly to return to their base to pick up some files, which was set to explode.
After failing to deliver Eggman to the Metarex they broke off their deal and captured Leon and his teammates. Leon and his teammates were later consumed by a tree and apparently died but not before giving Shadow the Hedgehog and Rouge the Bat information on the Metarex and their plans. Before Leon died, he knew that Molly was right all along after she left in the English version. In the Japanese version, he and his team watched in horror as she was killed by the Metarex.
