Background: Matt has psychic abilities, Tai's involve fire, and Davis' involve lightning. The Zenkyoshi grounds include a lake.
Matt looked at Tai smugly as a huge ball of psychic energy flew gracefully across the lake surface, dissipating as it reached the cliff wall on the other side. "Beat that Kamiya," he challenged with a smile.
Tai only grinned back. With a concentrated look on his face, he finally stood straight, both hands held out as he shouted a battle cry.
"Hyaaaaa!!"
A ball of flame formed, as the fire expanded and whirled into something that was barely contained. It shot across the lake, steam and waves forming in its wake as it went by. The fireball vanished the moment it reached the cliff wall.
Tai smirked. "I even had to stop it from getting out of control. You at that point?"
"What're you guys doing?"
Both boys turned to see Davis, looking at them inquisitively.
"Obviously, we're being manly and challenging each other at who's better with their crest abilities," Matt answered, shrugging. "Right now we're just shooting things across the lake."
Davis looked ecstatic. "Oo, can I join?"
"Sure, but - "
Davis went into a stance and a giant ball of electricity formed in the air.
Both Tai and Matt paled. "Davis, wait, not over the - "
"Hiyaaah!"
"… lake."
Matt had to teleport them out safely before the three of them were electrocuted.
