Danger was born in Copenhagen, Denmark and is a mutant with bio-electricity generating powers, and also an expert in bio-engeneering and physics. Little is know about his origin prior to joining the Euromind and Eurolab, although it is mentioned that he has some sort of criminal record: He has kept his real identity a secret from the Euromind with his face only being seen by one of his Euroforce teammates, only Key and Francois Borillon know his true identity and name [Dolph Dogen]. Likewise the fact that he depends on his suit to control his powers has resulted in him wearing his suit and by extension his mask at all times has contributed to this.
Whilst the nature of the crimes commited by Danger have never been mentioned, one of the victims of A.I.M. stated that they recognized him. This and the fact that he is a former scientist, may indicate some tie to Advanced Idea Mechanics.
After the disastrous mission in Malaysia of the Task Force, twin-team of the Eurolab, Danger and the newly formed "Euroforce" [formed by Eurolab and survivors of the Task Force] started to investigate the activities of Nadir Inc. and A.I.M., Euromind declared all members of the team outlaws.
After the events of the "Europa" story-line, Danger and the entirety of Euroforce had been declared dead, but continued to operate in the shadows as a covert operations team.
Being a mutant, it is highly possible that Danger lost his powers during M-Day, although this has yet to be proven. Danger does not appear in later incarnations of the team.
The body of Danger continuously generates bio-electicity, and as such Danger depends on a containmentsuitth to control the emission of electricity, and to prevent overcharching. Without the suit [or other forms of technological containment] Dolph will discharge uncontrollable bursts of energy.
The suit provides Dolph with some measure of protection, likewise it allows danger to utilize his electricity in many ways e.g shooting electric-bolts, charging his fists with electricity for use in close quarters combat and also flight. Danger has stated that the generation of electricity in his body grants him increased stamina and a low-level healing factor.
