'''Battle! Friends from Kalos''' (Japanese: '''勝負！カロスのともだち''' ''Battle! Friends from Kalos'') was a [[villain event]] in {{g|Masters EX}}. It tied into the first part of the {{DL|Villain Arc|Kalos: Team Flare Flares Up|Kalos chapter}} of the [[Villain Arc]], featuring battles against [[Trevor]] and {{mas|Tierno}}. It was one of the Kalos villain events, the other being [[Go, Go, Team Flare!]].

During this event, players could earn vouchers from battles against Trevor that could be redeemed in the {{mas|shop}} for rewards, including Legendary Spirits that could be used to raise {{sync|Professor Sycamore|Xerneas}} to {{6EX}}. Obtaining 2,000 vouchers would reward players with a {{mas|medal}}. All battles could be challenged an unlimited number of times except Daily Extreme Battle 1, which could only be challenged once per day.

This event featured the Battle Challenge, where players were challenged to defeat a team of strong opponents. Players could complete event missions by clearing these areas using various [[theme skill]]s, earning medals and other rewards.

All [[sync pair]]s with the [[Kalos]] theme skill received a bonus to their Attack, Defense, Sp. Atk and Sp. Def [[stat]]s when used for this event, with the amount of the bonus varying between areas.
