Dr Salvador Miguel was a low-level telepath with the ability to read people's surface thoughts.  He used these powers to do well at college, although he never deliberately cheated - it was more a case of being incredible sensitive to the needs of others.  He pursued a career in psychology, naturally, but tinkered on the side in electronics.  His powers were a blessing, but also a curse because they opened up such a wide world for Miguel but he was unable to fully access it.  His powers were simply too weak to do anything extraordinary beyond gleaning a few surface thoughts from people around him.

He decided to amplify his powers through electronics, believing that he could send pulses of electricity through his mind which would bolster his telepathy.  At first the experiments were promising, but when he attached himself to a large power source his luck ran out.  The source was too powerful and nearly fried Miguel's brain.  He was blown out of his apartment and into the street and the building caught fire and burned to the ground.

Some would say that such a catastrophe was a bad omen, but after Miguel regained consciousness several days later in hospital, he decided that he must have been on the right track so he tried again.  The power was too great again but this time Miguel electrocuted himself into a coma which lasted months.  During the coma, however, Miguel began to sense strange environments including a feeling that he was listening in on people's conversations and watching them from behind a screen.  Before he regained consciousness in the hospital, Miguel regained consciousness in the vast television network in Mexico.  He discovered that he could move around using the television broadcasts to appear in any number of television sets across the city.  He became desperate and called out to people watching the television, but they panicked and fled.

By sheer chance Miguel appeared in the apartment of the crime fighter, El Bruma Azul.  Rather than flee, the hero assisted Miguel find his body and once the mind was back in its place the doctor awoke.  La Bruma Azul spent a long time with Miguel as they both came to understand the breadth of Miguel's new powers.  It seems that his telepathy was gone, but in its place was a strange ability to project his consciousness through televisions and radios.  His powers had increased dramatically although he sacrificed some of his versatility in the transition.

Calling himself Dr Difusion because of his ability to 'broadcast' his thoughts, Miguel assisted the newly formed Defensa Suprema on many occasions before accepting full time membership himself.  He rarely ventures into the field and prefers to assist with co-ordination and information gathering from the safety of the team's headquarters.

Miguel likes to remain safely out of the harmful world of the uberhuman, although he readily assists his team mates with his television-based psychic powers.  As a trained psychologist, Miguel enjoys the intricacies of the human mind and works as the team's psychologist and counsellor.  He abhors widespread property destruction which the previous super hero team in Mexico was famous for, and he advocates diplomacy before any hard hitting, a philosophy which has led to some of the team considering him a soft liberal.  Miguel realises that some of the more physical members of the team assume his powers are weak, but he doesn't feel the need to prove himself.  He is a happy man who is able to mix his work with his pleasure.

"Please stand by for a very special news bulletin, proudly brought to you via the magic of television by the one and only Doctor Difusion."

Dr Difusion is able to project his mind into televisions and radios and has been known to appear on the screens of televisions in France, England, and even Australia.  Once inside the broadcast, Miguel is able to track down specific minds, focus his mental energy into a psychic blast or debilitating trance ray.  He enjoys finding new ways to use his powers but never steps out into a real battleground because he knows that it's not his physical attributes which make him formidable, but his mental ones.

A man who enjoys his life, Miguel is in his forties and enjoys fine food and wine which has led him to develop something of a paunch.  He has curly brown hair and bushy eyebrows, with dark green-rimmed glasses and a small goatee beard.  When he is using his powers his eyes glaze over with a white film and his face will appear on a television screen nearby or within range of his powers.  He never wears a costume, preferring comfortable casual clothing.  The face of Dr Difusion is usually only recognised on the television where it appears as a large blue skinned man with white eyes.
