The characters of the Lucas Leeverse, over 300 in all, were primarily created and designed by Lucas Lee and PurOrange; however there also units made by other artists, moderators, and fans. The units can be classified according to 2 factors: Rarity and Element.

Rarity

Rarity is measured in stars. The higher the rarity generally, the higher the power:

• Common: The easiest to obtain; however, they only appaer in Gacha Studio, Neko Gacha and Gacha Resort's shell gacha.
• Uncommon: A bit rarer and the 1-stars, also only appearing in Gacha Studio, Neko Gacha and Gacha Resort's shell gacha.
• Rare: The second most common characters in the games, appearing in almost every title. Their drop rate ranges from 20% in the above mentioned titles, to around 50% (varies by game, case, and gacha type).
• Super Rare: Rarer than the previous ones but appearing in almost all titles and generally have around a 36% drop rate (varies by game, case, and gacha type).
• Ultra Rare: One of the rarest, their rates are always pretty low. Their drop rate has a wide range from 20% down to 1.5% depending on game, case, gacha type, etc.
• Mega Rare: The rarest of most of the games, never higher than 3% and as low as 0.5% (varies by game, case, and gacha type).
• Legendary Rare: Only currently available in Gacha World. They are the strongest units of all the Lucas Leeme games and have the lowest Gacha Rate, this being only 0.1%
• Legendary Mega Ultra Super Rare or 10-Stars Units: The only character who belongs to this category for now is the Gacha Summoner.
