How would you build nemisis kid from legion
Various Absorb attributes and Parasite ... he's a pretty hard character to do.
Technically, he should be able to launch an attack using the vulnerabilities of the opposing character, such as fire against a character made of wood, electricity against metal, etc ... as well as being able to transform into the LEAST vulnerable substance when attacked himself.
Tough one! One idea would be to create several Shapeshifter forms, each one designed to match a general type of character: one that can stand up to bricks, another that's good against energy-blasters, etc. Then you can use A.I. subtypes to determine which form he uses. (I took a similar approach to Ultra Boy, since he can only use one power at a time. One temp form had just super-strength, another one had just invulnerability, etc.)
how do you use AI substybes, I could use this for several of my shape shifters.
Subtypes are explained in the FFX manual, in the M25AI section.
