Grade 2/Link Joker - Cyber Dragon/9000 Power/5000 Shield
Auto (V): When this Unit's Attack hits the Vanguard, choose 1 of your opponent's Rearguards, and Lock it.
Note that units returning from Lock are not entering a rearguard circle but are instead being flipped back over, so on-call skills like that of Gigantech Charger will not activate. Units which gain power from having other units on the field like Liberator of the Round Table Alfred and The Dark Dictator will not be able to derive any power from Locked units, as those units do not exist until they are turned back up.
