Kairi's whirlwind keeps the grasping root off Jack just long enough for Devero to step in. He drops to a knee and uses his prodigious strength to just tear the root apart. "Go!" he says as he stands, shoving Jack forward into the hole that Trunks and Kairi are starting to bore through the tree's defenses.

Devero-- who's no longer dressed in the Saiyan armor but rather something out of his past-- hangs back to keep that hole open. He's realized the utility of his strength, and sets to using both his hands and his two batons to not just parry the grasping roots and sweeping branches, but to break them.

He throws aside one snapped branch and throws up a baton to keep another from swatting the head and shoulders of a fellow passenger. "Keep moving, I've got this!"
