Prejudice can be a big challenge. Some people in the military or society may underestimate girl commandos at first. But in the stories, they often prove themselves through their outstanding performance in combat, intelligence gathering, etc. They also face challenges in terms of family. Balancing family life and the dangerous job of a commando is not easy.
In some fanfictions, they might use a time - traveling device created by a brilliant scientist. Maybe it's a modified version of a Stark - like technology that creates a time - warp portal.
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.
They might be amused. The fanfiction world can come up with some wild and creative ideas about Captain America, and the Howling Commandos would probably get a kick out of seeing these unique interpretations.
The creature in 'The Creature from the Never Ending Story' often represents the unknown and the fears that lurk in the fantastical world of the story. It can be a symbol of the challenges that the protagonist has to face, adding an element of danger and mystery to the narrative.
I'm not entirely sure about the exact appearance as it can vary in different interpretations. But generally, it might be a large, shadowy figure with glowing eyes, something that looks menacing and out of the ordinary.
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.
