I almost always use the same character, Strife, in my forum gaming. I've written a long, complexish back-story for him. However, part of the back-story involves him having a near-infinite number of previous adventures. I'll be writing them now.
For fun, I'll be using the TV Trope Story generator for the base of the story.
Before I start writing though, here are some baselines for Strife.
Strife is an Anarchistic Archetype. He is meant to largely be the classic hero sort. However, it's his gift/curse to be ever on the move. Imagine Sora flying around his gummi ship. Strife ends up on different worlds. Always in conflict of some sort. Being the hero that he is, Strife ends up trying to help. In the end, he eventually leaves the world. The exact mechanism of his world-jumping is unknown to him, although sickness often comes when he first shows up somewhere.
Strife is a pretty imposing individual (he IS the here, after all). First of all, Strife doesn't age. He can get stabbed, shot, sick, and hurt, but not old. He assumes that he can die; he's never tested it out. He has some skill at commanding and influencing people. Strife is generally average height with brown hair.
He sports a longcoat of some kind (it changes). The coat itself is the closest thing to magic that Strife has. First of all, it's a longcoat and quite warm. Second, it shows considerable bulletproof tendencies (although they tend to vary, call it about the equivalent to Frodo's mythril shirt). The pockets are also fun things. Effectively hammer space generators, Strife has stored a lot of stuff in them over the years. He tends to have a lot of trouble finding stuff if he's in a different world though. He can almost always produce one of his weapons from his pockets, thankfully. Strife has three preferred weapons. He is rarely without a combat or bowie knife of some sort. He is an excellent knife fighter. Mind you, even an excellent knife fighter will usually get his ass handed to him by someone with a sword.
He can also produce his M15 handgun. It's a heavy weapon, and fires .45 man stoppers. Depending on the area, it may have fun effects like infinite ammunition or a shotgun mode. He can produce additional clips for it at a significant energy drain. Strife is also excellent with handguns. He's deadly with his M15. Once again though, it's not much compared to someone with the next tier of weapons (I.E. a rifle).
The best (and least often usable) firearm that Strife uses is the M-14. It's a battle rifle with some enhancements to allowed continued automatic fire. He tends to use it as a single shot weapon, but has used it as a light machine gun. The same ammunition rules as the M15 apply.
Strife has lifetimes of experience with the martial arts. He is going to be as good as a journeyman with most weapons. Although, he may end up fighting against the local styles, to somewhat game breaking results (Quickly getting a stabbing weapon when everyone is using slashing things). If possible, he'll get a polearm in a pre-gun world. He retains special skills with knives.
He is able to quickly figure out most firearms (thanks to the laws of ergonomics). It may take a few minutes though. Strife can fight with most guns with the skill of an elite soldier. He's better with his preferred weapons by a considerably degree. He will prefer a longarm of some type if he can get
