Lucas also had a brief cameo in the opening of Giratina and The Sky Warrior, battling Brendan. In addition, concept art for Lucas' anime counterpart exist, suggesting Lucas was to play a bigger role in the main series, but this never materialized, most likely because a voice actor couldn't be found.

Trivia
- Lucas's Platinum outfit seems to be the inspiration for the coats that Ash and Brock wore when they visited Snowpoint City.
- Lucas' Diamond and Pearl outfit looks similar to Ash's regular Sinnoh outfit.
- In Pokémon Black and White when you first beat Cynthia she mentions Lucas. Referring to him as "That trainer who faced Giratina" she then admits she was rambling about things that didn't concern the current player. (It is assumed that she could mean either Lucas or Dawn)
- In Girantina and the Sky Warrior, his pants seem to be teal, while in Diamond and Pearl they are blue.
