During my scannerless time, most of my effort went into making a height chart for the Upperclassmen characters. Which, in several cases, actually involved designing some of the characters. Here, from left to right:

June Johnson, AKA Miss Mass: Obviously, the team's muscle. Super-strong, nigh-invulnerable, and loving it.

Jane Johnson, AKA Brainy Jane: June's not-quite-so-identical-anymore twin sister. Wields a multitude of mental powers, and finds herself in the unenviable position of being the team's straight-man.

Matt Schulz, AKA Cryoburn: An aspiring artist with power over fire and ice, with a temperament to match. Also the unwilling target of most of the team's more frightening female fans.

Tiffany Hamilton, AKA Bolte: Electrokinetic speedster. The universe conspires to make her seem like another bubbleheaded blonde, and it pisses her off.
