Ultraman: I, Tiga, Can Transform into Both Light and Darkness

[Ultraman fan fiction] + [Dark Tiga] + [Making up for a few regrets] After transmigrating to a world where monsters run rampant, I, Lu Chenye, have no System or Spark Lens, but I awaken the power to transform into Diga. Other people need to wait for light and shout a catchphrase to become Diga. I’m different: if there’s light, Light Diga crouches in the bushes and sneaks around behind the monster; if there’s no light, Dark Diga circles around in the dark and clubs the monster from behind! The first time I fought Golza, my teammates shouted, “Retreat and save your own skin!” I secretly transformed into Dark Diga and burst out of the ground, tearing its energy core apart with one swipe. The second time, when I ran into Melba, the base alarm was blaring. I used the light from a streetlamp to transform into Light Diga and “happened” to catch a falling passenger plane during a worldwide livestream. The comments all said, “Since when does Diga know how to ambush people?” When Chen Yanshan, the TPC captain, stared at me and asked, “Who are you, really?” and the mysterious organization Shadow Erosion hunted me down to seize the power of light and darkness, I shrugged. “Don’t panic. I’m just a Diga who likes taking shortcuts.” But who could have guessed that when light and darkness collided inside me and formed golden patterns, even Megumi Ayanokouji would widen her eyes. “Th-this is a form Diga has never had before?!”
