Hi Jab, I'm sorry not posting the Euroforce's info so far, but the net is surprisingly lacking any substantial info (luckily the marvel universe site has a pretty good sum of the story), and my old comic books have ended in the basement a long time ago, so I have to go by my memory only.
Like Gemini, Euroforce spawned from the Euromind - the SHIELD european division - but, while Gemini was looking for a sort of SHIELD patronage, EF was already a SHIELD unit at the beginning of his story arc, or rather two units.
(the events are likely to take place during summer 1994, like those of Gemini but there is no official mention of any date)
Euroforce began as two teams, Eurolab and Task Force. Eurolab was a scientific recon group composed of Key (Geyr Kluge), former S.H.I.E.L.D. science officer and team leader; Danger, a mutant and second-in-command; cyborg Deep Sight (Jane Melville); telepath Nuage (Silvie Rouge); and Picaro (Antonio Rey), communications specialist. They were dedicated to studying paranormal phenomena for Euromind, a research agency and off-shoot of S.H.I.E.L.D. funded and controlled by the mysterious society known as SHAPE. Task Force was a special S.H.I.E.L.D. division loaned to Euromind for use in emergencies; its members included Dragonfly, armored soldier Blue Condor, Argento, armorskinned Tiger and weapons man Iceboy. Key viewed Task Force as heavy-handed barbarians with no sense of scientific values; in return Dragonfly resented her unit "baby-sitting a Boy Scout troop." Both teams reported to Euromind's Director Borillon. Their first recorded joint mission was investigating monster sightings at a Spanish archaeological dig. They discovered descendants of Inhumans who had been thrown by the Inquisition into an underground cave system to die; when the Inquisition subsequently disposed of the remains of a crashed Skrull ship and its crew the same way, the Inhumans had feasted on the dead aliens, and transformed into monstrous metamorphs.
Eurolab rescued survivors from an Italian jumbo jet that had splashed down after a passenger transformed into a rampaging monster. As it began to sink, Damage located the metahuman; no longer out of control, he refused to be saved, claiming he preferred to die rather than be recaptured by the people behind his metamorphosis. While investigating reports of artificially mutated humans in Malaysia, Task Force was attacked by the cyborg soldiers the Lords of War, who slew Dragonfly and Blue Condor; Tiger and Argento retreated, but Iceboy was captured. Back at base, Key and Tiger were told SHAPE had ordered an end to the investigation into the origins of the mutates. Eurolab and the surviving members of Task Force decided to return to Malaysia and find Iceboy; their meeting was secretly monitored, and as they departed, armed Euromind agents tried to detain them. They escaped, but some of the Euromind agents opened fire on their fellows, framing the errant squads for the killings; Borillon soon saw through the ruse, but was unable to prove the truth.
The squads, now united as Euroforce, tracked Iceboy to the labs of French multinational Nadir, which proved to be an A.I.M. front. While the bulk of the team held off both A.I.M. agents and the Lords of War, Tiger and Key breached the maximum security section and found a dramatically mutated Iceboy. A.I.M. agents burst in and shattered Iceboy's gestation tank with gunfire; Iceboy quickly defeated the agents, but died seconds later because the process had been interrupted. Key and Tiger reunited with the others, who had evaded the Lords of War, and Euroforce fled. As they flew away, their plane was attacked by the Lords of War and exploded; though SHAPE believed them dead, they survived and, secretly allied with Borillon, are planning their next move.
Since the two teams have quite different specializations I listed them separatly
Key (Geyr Kluge):
Eurolab field leader, Key is a former field scientist of SHIELD with no known superhuman power but a lot
of years of experience. He was portraied as an highly athletic man, a capable startegist and a genius field researcher, his main weakness is a slightly lack on the tactical abilities. Even lacking any power Key displayed a prodigious memory - he was able to recall by the word long pieces of Reed Richards' writings - and an amazing knowledge of languages both human and alien (he speaks, understands and reads german, english, italian, spanish, french, inhuman and skrull for sure). Key is a scientist first and foremost he hate violence, but he is more than willingly to defend himself, and unnecessary destruction. By the rules point of view Key is the quintessential adventurer, the only possible power for him is a Comprehend (all langueges speak, understand and read) to represent his extensive ability with languages.
Danger (real name unknow):
Key's second in command, Danger is a mutant capable of generating powerful blasts of an undefined energy type, while in certain panels it looks like that he is able to fly it's unclear if he can or it's only a graphic license. Danger wear a sort of contaiment armored suit all the time, apparently he isn't able to control his powers without it (it was hinted that he is no longer flesh and blood, but only a mass of energy kept together by the suit). Of all the members of Eurolab Danger is the most likely to have a paramilitary training, since it was supposed to be part of Task Force in the first place. Danger is portrayed as a no nonsense character, he uses his powers to get the job done with minimal collateral damage, while he doesn't like to use them as a weapon, usually keeping his own powers in check fearing to lose control, like Key he is more than willingly to defend himself. Another straight character Danger is an energy controller with a peculiar BG.
Nuage (Silvie Rouge):
the team "first contact expert", Nuage is a quite intersting psionic character. She displayed the standard Marvel psionic package (Telepathy, Telekinesis, Emotion control etc.) but the details set her apart. First Nuage TK is surprisingly weak, she isn't able to manipulate a weight greater than 100 Kg (more or less), but that's enogh to make her able to fly at low speed. Second her telepatic powers are more empatic in nature, she is able to project and perceive emotions in a vast area around her, but her mind reading is limited to a single mind at a time, even if she can execute a quite accurate and in depth scan. Third she possess a quite powerful psycometry (quite a useful power for an archeologist), that combined with her telepathy make her able to read a cyborg's mind and data banks at once. When she use her powers a small energy orb appears near her, the orb colour seem to reflect her emotional state, usually it's light blue or green, the angrier she gets more the orb's colour moves toward red. Nuage is portrayed as the second most learned character, after Key, and a pacifist at the heart. She rarely enters a fight prefering to use her powers to calm her opponents, she is also extremly carring towards any innocent bystander (in #0 she risk her own life to save a pregnant moloid woman).
Deepsight (Jane Melville):
Deepsight is a cyborg with the left half of her body replaced by adamantium prothesis. She is the team tech girl and powerhouse (probably the right half of her body is internaly reinforced). Deepsight have a distinctive lack of empathy and emotions, it's unclear if this is a result of her cyborged state or a trait of her personality. Among the other devices implanted in her body she had a radio, an infrared/telescope/telemeter (in her left eye), a parabolic microphone and a tactical computer, also she was able to interface with computers or other equipment designed to accept her human/machine interface programs, like SHIELD's (she can't do a Deathlock style datalink). In at least two occasions she was able to survive fall without any significant damage by absorbing all the impact on her left leg. Due to the different density of her two halfs Deepsight have some trouble with balance feats and need a specificaly tuned climbing equipment. While Deepsight is a quite attractive girl, her emotial lacks and the metal plating on her body makes her less attractive in the eyes of the opposite sex, apparently Picaro is the only one not concerned about these issues.
Picaro (Antonio Rey):
Eurolab comunication expert, Picaro is mutant with the ability to generate electrical energy from his own hands, this ability also speed up his nervous system giving him a superior degree of muscle control. While he can use his power as a weapon he rarely do so since it apperars to be quite tiring. Picaro is portrayed as quite a showoff, with a personality very akin to Gambit. He has a crush on Deepsight, but she appears not to like him (or at least not showing it).
Task Force is a military unit that takes its members from some of the finest special forces of Europe.
Dragonfly (real name unknow):
the highly aggressive team leader, like Key she has no power but she is highly trained soldier and commander, she is particulary good at improvising on the run tactics, that makes her the natural complement to Key more intellectual style of command. She has several years of experience as a SHIELD's field agent, and before she was part of an unnamed special forces unit (probably KSK - Kommando Spezialkräfte, the german special forces - based on some hint by Key). Like the rest of her team, she packs a vast arsenal of weapons, but her signature weapon is blaster rifle with an underbarrel grenade launcher. It was hinted that Dragonfly and Key have a long backstory, and that they probably loves each other as persons, but loath each other work. She is the most flamboyant and aggressive of her team, both her temperament and her skill looks like 2/3 Domino's and 1/3 Rogue (classic version).
Bluebird (real name unknow):
a former SAS member, Bluebird is equiped with an armored exoskeletron capable of agumenting the strengh of her limbs by several Gs, making her able to throw a punch through a vibranium-steel armour or making leaps hundreds of meters long. Unfortunatly she was the most underused character of the entire team, so I don't have clue about her temperament.
Iceboy (real name unknow):
Task Force heavy weapon expert, Iceboy is the only non european in the team, he is canadian. Iceboy have no powers of his own, but he is a super skilled soldier (it was hinted that he had a sort of nanomachine network that protects him from extreme temperatures and speed up his recovery, but this note was never consistently backed up). His signautre weapon is a 5 barreled gatling gun, but he was described as able to use any modern firearm or explosive equally well. Iceboy is a direct no nonsense soldier, he knew when to fight and when to retreat, he is also the best friend of Tiger.
Argento (real name unknow):
the team infiltrator and sniper Argento (the italian for Silver) is an albino soldier from the GIS (Gruppo Intervento Speciale - Special Intervention Group - the italian anti terrorism unit). During the series he discovered to be a mutant with the ability to make himself impossible to perceive, meaning that he is invisible to various visual, auditory, olfactory and telepathic senses, and to some radar sensors. While this ability complemented his own natural skill, Argento doesn't cope so well with his new condition. He was potrayed as quite a loner, a trait that was exacerbated by his specialization and his mutation. In combat the rest of the team rarely knew where he is, but they seem to rely on th fact that he will be around for help. His training makes him an expert with long range rifles and close combat weapons (mainly knifes, light pistols or SMG), his skill with other weapons are less developed.
Tiger (real name unknow):
the team brick, Tiger is a eight feet tall hulking soldier with a layer of impenetrable skin grafted over all of his body. This skin looks akin to the external layer of Rhino's armour. He was trained by SHIELD and hinted that worked under the direct command of Nick Fury in a couple mission, before joining the Task Force. Tiger is a veteran soldier, with a way of thinking very close to Iceboy, he seem to get along quite well with Danger too. Statwise tiger is a brick/blaster combination (thanks to his size he can swing around some serious firepower, since he can wield an heavy machine gun like an assault rifle), while his size and muscular density makes him stronger than a normal human being, he distinctivly lacks superstrengh.
Some of the team members (from left to right):
Deepsight, Danger, Key, Argento, Nuage (in front of the others probing someone), and Tiger.
Euroforce lacks any world class superhuman, as singles they are truly weak, but they tend to work together extremly well (even better than the X-men), and displayed an amazing level of teamwork. Also they have a lot of formal military or paramilitary training to back up their powers, making them a lot more dangerous than the standard superhumans without their powers. They are also a lot more stable than Gemini, and more experienced.
Euroforce also had a truly international feeling, Key (and probably Dragonfly too) is German, Danger is from Belgium, Nuage is French, Deepsight and Bluebird are from the Great Britain, Picaro is Spanish, Argento is Italian and Iceboy is Canadian. Tiger origins are undefined, but he is probably from the USA.
