In the console versions of the Skylanders games, the small colorful globes left behind by enemies or when winning an arena match are called Victory Points. When enough points are collected, the Skylander will gain a level up. In Skylanders: Spyro's Adventure, Skylanders can use Victory Points to get to the game's highest level: 10. In Skylanders: Giants, Skylanders can use the points to go to the highest level in that game: 15. In Swap Force, Trap Team, and SuperChargers, 20 is the maximum level cap.
Furthermore, as of Swap Force, all Victory Points collected in two player co-op are given to both players equally.
In the 3DS version of the series, the Skylanders upgrade by leveling up.
