Alternate versions of Darren Appleton
In Legion of Lawndale Heroes, Darren was dating Natalia Lucchini; however, his uncle William Appleton had orchestrated events so that a shapeshifter (in Darren's form) was keeping her occupied. This was because the real Darren has been comatose for almost one year, after being exposed to a skunk which was one of the remaining animals left after the Animal Liberation Front raid on a animal research facility overseen by the Appleton family.
