So here's this - a randomly-generated type chart. This has gone around a bit on the Smogon subforum I'm in from a random type chart generator I made. If you were to fill this out with fanmade types of any kind, how would you do it? For example, here's mine... Spoiler: Mine You can do what you want but for the project I did this for, I couldn't use existing types. Some stand-ins exist. - Rock, Paper, Scissors is a fun thing to center this around, so Stone, Paper, and Blade is the main type triangle here. - Crystal beats Stone and loses to Blade because Haunted suggested I put Ice here, and some crystals share similar properties. Easy to shatter, hard to slice. - There's potential for a type square here between Stone, Paper, and two others, and I felt Glass and Heat fit here. Stone shatters Glass, Glass is Heat-resistant, Heat ignites Paper. - Plastic is tough enough to make things like mallets that can smash glass, and you can use Heat to melt it. - You cut food with Blades and Plastic is used to contain them so I kept thinking of food-related types. Sweets would be fun to work with here. - Brawn is a stand-in for Fighting, like Heat for Fire and Stone for Rock. Brawn beating Stone is self-explanatory but muscledudes have to avoid Sweets. - Finally, the neutral type, Tooth. They decay, but I might change this, since the other way around could also make sense. This takes a while and is kinda difficult to make things fully cohesive, but try it out!
