Trans-Scan combines the Robot Mode and Alt Mode cards of a Transformers character. This can only be done when you have both Robot Mode and Alt Mode, multiple robot mode cards cannot be Trans-scanned together and neither can multiple Alt Mode cards. The result is a stronger card that can change modes and receives a larger bonus (15%) during battle.
When you initially discover a card, it will be at level 1. Each rarity level has a maximum level that it can be upgraded to. A card that is Trans-scanned at anything less than maximum level will add 5% of the current stats when Trans-scanning, but a fully maxed card will provide 10% of the current stats. Therefore, ensuring that both your Robot Mode and Alt Mode cards are fully maxed prior to Trans-Scanning will provide the greatest boost.
As soon as you have discovered both forms of a card, you will be prompted to Trans-scan them together; this setting can be disabled in the "Options" menu. It is strongly advised that you upgrade both the Robot Mode and the Alt Mode to maximum level before performing the trans-scan in order to get the largest stats increase.
Max, Trans-scan, Max (MTM)
Bringing both Robot Mode and Alt Mode cards to maximum level before Trans-scanning, Trans-scanning and then bringing the combined card to maximum level is referred as max, Trans-scan, max: (MTM).
In a Trans-scan at max level, the trans-scanned card is 50% stronger than its robot-/alt-form and receives additional 10% of the stats from the cards offered during Trans-Scanning, which results in a 70% stat bonus*, also the Transcanned card will be lvl 1 again.
There will be a star on the card indicating that the card is at max level when MTM is completed successfully.
Trans-Scan-HP/ATK/DEF* = LVL1-HP/ATK/DEF × 1.5 + ( 2 × MaxLVL-HP/ATK/DEF × 0.1 )
When the formula is applied to a level 65 Trypticon (1) card, it will be as follows:
HP: 7600 × 1.5 + ( 2 × 16800 × 0.1 ) = 14760
Trans-Scanning below Max-Level
In a Trans-scan at lvl 1, the trans-scanned card is 50% stronger than its robot-/alt-form and receives additional 5% of the stats from the cards offered during trans-scanning, which results in a 60% stat bonus*.
Trans-Scan~HP/ATK/DEF* = LVL1~HP/ATK/DEF × 1.5 + (2 × CurrentLVL~HP/ATK/DEF × 0.05)
When the formula is applied to a level 1 Trypticon (1) card, it will be as follows:
HP: 7600 × 1.5 + ( 2 × 7600 × 0.05 ) = 12160
