[ Adding a system for determining a monster’s attributes from its picture. This gives us a number-of-mutations total which might make a nicely two-edged “combat ability, but also perceived military threat level”, but I’ll leave it open for now. ]

If “Monster Attributes” passed, repeal the rule or section that it created.

Enact a new Rule, “Mutations”:-

Each Giant Monster may have one or more Mutations; these are determined from the image of the Monster, and are listed as text in the Monster Roster. Tokyo may, at any time, refer to the following list and assign Mutations to Monsters as appropriate. (Tokyo’s decision is final, in deciding whether or not a Monster possesses a particular Mutation.)

• If the monster is emitting fire from its mouth, then it has the Fire-Breathing mutation.
• If any part of the monster seems to be glowing, then it has the Radioactive mutation.
• If the monster is standing on top of a building, or climbing one, it has the Agile mutation.
• If the monster is entirely in the air, it has the Flying mutation.
• If the monster is partly or wholly immersed in water, then it has the Aquatic mutation.
• If the monster is taller than a building visible in the picture, it has the Gargantuan mutation.
• If the monster’s body has some metal parts, it has the Robotic mutation.
• If the monster has red eyes, it has the Evil mutation.

A Monster’s Threat Level is equal to the number of Mutations that it has.
