Not a terrible idea but parts of that wouldn't work too well since my idea was that he would go directly to fight the guy and he has no money since being raised in a lab he has no concept of monetary gain so the idea of hiring mercenaries is out. That said you're definitely onto something since I already put where a couple of other subjects are designed to fight their designated targets in a more tactical approach by either rendering their main powers and weapons choice obsolete and taking advantage to their usual fallback plans, one being the daughter of the engineers of group who once again is weaker than her parents but compensates through using advanced martial skills that they don't have and rendering their weapons and gadgets useless. So maybe setting where this guy focuses on keeping his distance while rendering range weapons obsolete could actually since him fighting his target is a gamble anyways.

(Continue) Plus I can add it where he has built in traps like bear traps or a harpoon gun that he can deploy and use when his target is either distracted or off guard and can use these to slow him down or incapacitate him altogether. Or even put it where the traps are on him and he uses them when his target is close then fires away with his spikes. Plus he's not even a final product anyways since the people in charge of the project had intentions of breeding another subject to possibly replace him but still that he might be good enough to eliminate his target so maybe put where he's incomplete or just a stepping stone. Either I do like some of the ideas you're presenting, I especially the name you're using too, Char, I might use that, if not for this character than at least someone cause that's pretty neat name.

Neat plotline ideas of yours! Just for clarification: I meant Char as a shorthand for "Character" (=Main Character / Protagonist) but you're welcome to use that as name if you like it, of course! Same for the other ideas, pick or modify what you like and see as useful! :)

Oohh ok that makes sense I thought you meant char as in charred or something but either and yeah no like I said I definitely will take in your input since yeah some of them may not as well but you definitely know what your talking about and definitely had some good ideas especially since part of the idea is that those who aren't on the physical level of the members of the group do rely more of a tactical approach out of necessity so either I appreciate your ideas

I had another idea to get to "mercenaries" without "hiring them": If there are others on the spot where the encounter between char and target takes place, char could try to have target annoy those, so they fight with char against the target.

Example: There are policemen (you need to replace them maybe with someone else, I do not know enough about your story). Char moves close to them but in a way target cannot see the police. Target shoots at Char, but policemen notice that and intervene, siding with char (unknowingly).

Antares‭ hm yeah makes sense since this guy is highly trained and will likely take any advantage he can in order to win this fight, plus there are few thing I didn't mention mostly because it wasn't relevant to the question

1. The test subjects were equipped with a special techno organic device in their brains that allow for direct communication to each other through what is known as the "battle net", sort of like telepathy, so if he's really in a situation where it turns out the target is doing better than expected he can call for help and someone who has some level of immunity to his powers and weapons as well or at least has something to make it so its not something to worry about can step in and help overwhelm the target.
2. It's a little difficult to get into too many details without just putting practically the whole story here but to summarize he and some other subjects escaped, leaving behind those too indoctrinated to join, and after that those who escaped eventually were..

(Continue) convinced to help tear down society as revenge, and Parr of the grand scheme was taking over the criminal underworld and while he's not in charge, being a part of the group, that for now I'll call the pariahs for context, he does at least act as something of an enforcer, so yeah maybe if the called foe it and the larger group found out and sent the target, the char could order those thugs to help in the fight or more than anything slow down the target so not entirely out of the question, plus some other of the pariah include a cyborg who has sound based weaponry and girl with vibration powers as well nigh invulnerability so I those guys weren't busy they could easily help him out The thing us part of the story involves a final confrontation where the pariah end fighting their designated targets, and the char does give his target a hard time, with him only because of circumstance but yeah I like I said your idea isn't out of question entirely
