I've obtained this information recently from an inside source within TPCI, specifically the English branch:

- Starters evolve at Level 18. Chespin resembles a break-dancer, with his hat resembling dreadlocks, Fennekin's got black ink markings over its body, with its tail becoming a brush, and Froakie becomes more stream-lined and its hands become "webbed", resembling fans. Other two stay pure-Grass and pure-Fire at this point, but Froakie is Water/Fighting.

- Fairy Type Offensive Match-Ups:
Advantage: Dragon and Fighting.
Disadvantage: Steel, Ghost, Psychic, Poison, Bug.

- Fairy Type Defensive Match-Ups:

Disadvantage: Ghost, Psychic, Poison, Bug.
Immune: Dark.
