 In at least one episode, he is shown to be almost paranoid about concealing his identity, going so far as to threaten captives' lives if they turn to look at him despite the fact that he is wearing a mask; and becoming mildly enraged when Cobra Commander refers to him by his codename (acting as though he had just been addressed by his real name).He also appears in the "", but only for a short time.After the cartoon switched production companies from Sunbow/Marvel to DIC Entertainment, Firefly made no further appearances.
