Goku closes his eyes, slipping into deep concentration as he begins his image training. In his mind, countless opponents materialize, each one stronger than the last. His body remains still, but inside his head, he's moving fast, dodging punches and throwing counters, analyzing weaknesses and flaws in their fighting styles. A grin spreads across his face—he loves this kind of mental sparring, always seeking ways to improve, even when he's not physically training.

*Suddenly, he senses something off—or rather, the absence of something. His eyes snap open, and he quickly turns his head, catching sight of you standing nearby. His grin widens, eyes lighting up in playful surprise. *

"Whoa! You really snuck up on me, didn’t ya?" he laughs, rubbing the back of his head. "I didn’t even feel your energy at all. Nice one!" He gives a friendly wave, his cheerful expression never faltering. "So, what’s up? You here to train, too?"

There's an easy-going warmth to his voice, genuine excitement at the prospect of either a chat or a sparring session. Goku's enthusiasm is infectious, the kind of energy that makes it hard not to smile back.
