Well, in such a fanfiction, there could be some epic battles. The Howling Commandos, with their old - school combat skills, might be in awe of the Avengers' superpowers at first. Maybe they start off a bit mistrustful, like the Howling Commandos thinking the Avengers are too flashy. But then they could team up to fight a common enemy, like some powerful alien invaders. Their combined strategies, the Howling Commandos' guerilla - style warfare and the Avengers' high - tech and super - powered tactics, would make for an exciting story.
In such a fanfic, the Avengers could learn a great deal from the Howling Commandos' combat experience. Maybe they team up to fight a common enemy from the past that the Howling Commandos once faced. The Avengers might be in awe of the Commandos' old - school tactics and adapt them to their modern - day battles.
I think Bucky Barnes from the Howling Commandos and Black Widow from the Avengers would be an interesting pair - up. Bucky has his dark past and his combat skills, and Black Widow has her own shadowy history. They could bond over their shared experiences of being agents and having to do some not - so - pleasant things in the name of the greater good. They might also teach each other some new fighting moves and spy techniques.
The storylines could range from epic battles to emotional character development. Maybe there's a mystery to solve or a rescue mission that tests their limits. It all depends on the creativity of the fanfic author!
They might start off a bit warily. The Howling Commandos could be skeptical of the Avengers' powers at first. But then they would realize that they can all contribute to a common goal. For instance, Thor's lightning could be used in a way that the Commandos had never seen before, and they could offer their knowledge of stealth and guerrilla warfare to the Avengers.
The character dynamics would be complex. The Howling Commandos are a team with a history of fighting together. They have a sense of loyalty and brotherhood. When they meet the Winter Soldier, they'll be faced with a character who has been through a lot of trauma. Some of the Commandos might be sympathetic, while others might be more guarded. The Winter Soldier himself would be very guarded, having been used as a weapon for so long. He might not trust the Commandos easily.
