User blog comment:King Flurry51/Izzy:Popular Underdog or Forgotten All Star?/@comment-35640410-20141018192141

I don't consider Izzy an underdog but more of an in-between contestant since she only merged once despite competing in all 3 seasons.

For me, underdog characters and All-Stars vary depending on generation. Underdog characters as far as the first generation cast go to me are characters who only competed in 2 seasons and either merged once or not at all. All-Stars characters from the first generation to me are characters who competed in all 3 seasons and merged at least twice. (I find it odd why they didn't include Leshawna but they basically needed 7 from the first gen and seven from the 2nd gen). As far as the 2nd gen goes, to me it's characters who actually merged while anyone who didn't is an underdog. I'll pretty much give the basic details on why each character was brought back for All-Stars:

Alejandro - He only competed once in the first generation, but I'm guessing since he merged that's why they brought him back and to also balance things out.

Cameron - Merged in his season 4 participation.

Courtney - Competed in all 3 seasons and merged twice.

Duncan - Won a season, merged 3 times and competed in all 3 seasons.

Gwen - Despite only merging once at the time, I would assume it's because she won a season and competed in all 3 seasons.

Heather - Competed in all 3 seasons, merged twice and won a season.

Jo - Merged in her season 4 participation.

Lightning - Merged in his season 4 participation.

Lindsay - Competed in all 3 seasons and merged twice.

Mike - Merged in his season 4 participation.

Sam - Basically used to balance out the TDRI contestants

Scott - Merged in his season 4 participation.

Sierra - Pretty much the same deal as Alejandro

Zoey - Merged in her season 4 participation.
