Cross Stride (クロスストライド Kurosu Sutoraido) is an official term introduced in G Booster Set 4: Soul Strike Against The Supreme, which refers to G units who require a specific, different G unit face up in the G zone, either to gain a bonus or to be able to activate their ability, or turn it face up for the cost of their ability.
"Cross Stride" can be viewed as a Cross Ride variant for G units, but needing a different G unit in the G zone rather than in the soul. Also, turning the unit face up to pay the cost of their ability is similar to G Persona Blast, but oriented to a different G unit in the G zone.
