[Multiple Heroines] [Almost Invincible] [Ben 10 Alternate Universe] [Turn Kiana Straight]
The protagonist, Tian Xiaoban, wasn't originally called Tian Xiaoban. While watching Ben 10, he was transported to its world and became Tian Xiaoban. He lived much like the original storyline, but his personality was different from the original Tian Xiaoban's. He ended up using nearly every alien hero with offensive abilities, and his favorites were Electric Lizard, Way Big, and Alien X.
At sixteen, while pursuing an enemy who didn't exist in the original series, he was suddenly caught in a space-time rift during the arrest and sent to Honkai Impact 3rd.
There, he made new friends who could also be called girlfriends, though he could be rather clueless about romance sometimes.
And now, the heroes make their entrance!
Heatblast: My flames are seriously hot.
Ghostfreak: Stay away from me, or you'll freeze solid. Don't expect me to be able to help you.
Wildmutt: I can devour all matter in the universe.
Way Big: You'd better not mess with me.
Alien X: I wield a power that's practically omnipotent.
Electric Lizard: You'd better not fire energy blasts at me.
I hope this comprehensive list is not a weakened version
