During the long years of relative solitude before and since their discovery on the Moon by the larger Transformers, Kobushi came to the conclusion that personal perfection could be attained through challenging combat. Every enemy destroyed, he believes, adds to his own power as a warrior. He has devoted his life to improving his martial skill, adapting the ancient art of Metallikato to most effectively use his diamond tipped drill arm. Landslide, the toughest individual on the Exploration Team, has been his frequent opponent, and Kobushi challenges him at every opportunity.  

...

Landslide is at peace always. His long contemplation has taught him the path to inner stillness. He has let go of the physical world, and embraced the world beyond. Recently, he has discovered how to project his core programming out of his robotic body for a limited time and into astral space. There, he has encountered other, powerful beings, and learned many truths. Though Kobushi attempts to interrupt his meditation at every opportunity with petty challenges, Landslide has yet to fall before the aggressive robot's attacks, using his inner strength and passive nature to create the ultimate martial defense.
