Undertow came to MARS as a marine vehicle engineer. He began training with The Iron Grenadiers in his spare time. As he learned battle tactics his designs became more battle ready. As a side effect, Undertow had to take a more hands on approach with training The Iron Grenadiers to use his weapons. After Destro saw Undertow leading the training exercises, he gave Undertow command of marine operations for the Iron Grenadiers.
