Nicholas Steel is a primary character who appears in the Ella-Metals series whom first debut in Ella-Metals: Run For Your Life!, in the training mode. But, he gets a story mode in Ella-Metals 2: Machine Attack. Despite his name, he has no relation to the Metals. He works with Ella as a teacher for a Summer Job to help Ella improve her Metal manipulation skills. During the events of Ella-Metals 2: Machine Attack, Samuel Think (his rival) finds out through the local news that Nicholas is missing and last seen at a Raven Facility. Thus, Ella and Co. begin to investigate further into the case. He appears in a yet to be confirmed mission in Ella-Metals 3. Steel's son is Martin Breeze, but Martin inherited his mother's power instead. This was revealed in that very same mission in EM3. He is retired so is assumed to be in his 60's.
Nicholas is focused and calm and is similar to Think with mild wise-cracking sarcasm.
Nicholas has balding grey hair and is of tall, broad stature.
