Jay Null

The engineer and creator of Wing Gundam and Heero's mentor, he is an expert in the field of beam weaponry. His distinguishing features include mechanical-looking goggles and a cybernetic right arm. Quirky but affable, Doctor J is immensely proud of Heero's abilities and encourages the young man to choose his own fate, including protecting Darlian and rejecting Operation Meteor. It was J who chose Heero's codename, which he thinks is highly appropriate. He also saves Relena from OZ's hit squad and tells her about Heero's past. He was killed with the other scientists (and Quinze) when they re-activated Peacemillion's engines to propel Libra way from Earth. Doctor J is voiced by Minoru Inaba in the Japanese language and Dave "Squatch" Ward in the English language.
