It's not too complicated. You need to go to the settings of VS Code and look for the font options. There, you can select Comic Sans from the available font list.
One interesting concept could be the clash of different universes' rules. For example, when Sans from the Undertale universe meets characters from other crossovers, the way their powers interact. Sans' unique abilities like teleporting and bone attacks might be affected by the new environment or powers of the crossover characters.
Papyrus also shows up often. His relationship with Sans adds an interesting dynamic to the crossovers. And his own unique personality and abilities can lead to various plot developments when combined with other crossover elements.
It's really hard to say. RWBY characters have a wide range of abilities and combat training. Ruby is super fast and has a powerful scythe. But Sans has his magic like his bone attacks and dodging skills. I think it would depend on the situation. If it's in an open area, RWBY characters might have an advantage with their long - range attacks. But if it's in a more enclosed space, Sans' teleportation could give him the upper hand.
Well, one interesting plot point could be the clash of different powers. RWBY characters have their unique abilities like Ruby's speed and Crescent Rose, while Sans has his bone attacks and teleportation in the Undertale universe. Maybe there's a moment where they have to team up against a greater threat despite their initial rivalry, which would be a cool plot twist.
Toge Inumaki is important too. His special cursed speech ability makes him stand out. Also, the principal of the school, Masamichi Yaga, is likely to be important as he is in a position of authority and has an influence on Gojo and the other students. There could be other characters like the members of different clans that also play roles in the complex web of the story.
