He might break the computer. Doom Guy is known for his strength, and a punch from him could easily shatter the screen or damage the internal components of the computer.

One popular 'Overwatch Reacts' fanfiction could be the ones where the Overwatch characters react to different timelines or alternate universes. For example, they might react to a world where the Omnic Crisis was never resolved. Another could be their reactions to new heroes joining the team. It's all about exploring the characters' personalities through these reaction scenarios.

Sure. Fanfiction writers often come up with the wildest crossovers, and 'Naruto is the Doom Slayer' is one of those really creative ideas. It might explore how Naruto's chakra powers could be used in a way similar to the Doom Slayer's abilities, or how his ninja - like agility and combat training would fare against the demons in the Doom universe. There could be all sorts of interesting plot twists and character interactions in such a fanfiction.
