Re: How would you build Mr. Fantastic's or Plastic Man's movement?
someone with 20m stretching and 12m running would cross a 20m chasm thusly
phase 1: stretch and grab wall (or something) on onther side
phase 2: move 12m across chasm. (at the end of this phase, the bulk of the character is 12m across with one part (a leg or his legs or something) stretching back 12m to the start of the gap.
phase 2: move the remaining 8m. since this is more than 1/2 his move, he has yet to disengage his limbs that are stretching back to the start.
phase 3: disenguage his stretched limbs.
phase 4. continue down tunnel.
