Hiro has been distancing himself from his friends and family, and Tadashi won't rest until he finds out why. When he learns the truth, he will do anything to heal his brother and put that smile back on his face. TRIGGER WARNING: Rape/Depression/Self harm/PTSD . *COVER BY RAZZLEPAZZLEDOODOT. THANK YOU, FRIEND*

The summer Tadashi went to robotics camp was the summer his parents and four year old brother went on a cruise. The boat sank, and his family was assumed dead. Ten years later, a lone boy is found on a deserted island. Tadashi wants so much to reconnect with his brother, but Hiro remembers so little, and he's afraid. What hardships await the brothers?

(Hocus PocusXBig Hero 6 (Pre-story)) For his senior year, Hiro will go on a trip to Salem, Massachusetts. Because he's so young, he has to select a chaperon to go with him. As one would expect, he'd choose Tadashi. The Hamada brothers go to Salem Massachusetts together and everything goes well, up until they find the abandoned museum and stir up some trouble. (Rated T)

After helping Tadashi Hamada back home, due to an accident with Baymax, Honey Lemon finds herself alone with him at the Hamada house... or so it starts out that way...

Follow fraternal twins, Tadashi and Ethel Hamada through their lives.

Based on a cool theory. Info about theory in chapter 1. Hiro is in a coma, after the incident at the SFIT Showcase. Day after day, his friends and family visit him hoping he will wake up.

Tadashi and the rest of BH6 was caught in a high speed chase with The Fujitas when they find out that they stole an important invention from Krei Tech. They retrieved the invention only to find out that it's not a piece of technology at all but a young boy named Hiro. Technopath!Hiro Alive!Tadashi. A few scene from the movie.

When Hiro gets forced out of the house on his day off from school, he doesn't expect to meet the first person his age that he could actually call a friend. However, it doesn't take long for him to notice that there's more to his new friend than meets the eye. That doesn't scare him though, because Hiro knows that she's worth it. AU where Tadashi is alive Hiro x OC

One night, on Friday the Thirteenth, Hiro decides to spend all night at SFIT with a Ouija Board. Rated T because it will probably be scary in later chapters.

Tadashi just thought it would be an average evening where he'd, for once, could come to work in the Lucky Cat Café with his parents. But when two masked men suddenly come out of the blue, he wished they just had closed the shop... something I came up with while watching a show on TV, based on a real story.

Tadashi didn't believe in ghosts, but it was hard not to when he was all the proof he needed. After he dies in the fire at SFIT, he finds himself unable to be heard or seen by his grieving loved ones. Only later on did he find out that he wasn't as helpless to comfort his family as he thought. He was starting to learn that he could interact with the living in a very... unusual way.

Tadashi Hamada is the new kid at SanFransokyo Elementary School. He's just lost his parents and now lives with his aunt and three (almost four, Tadashi!) year old little brother. Luckily, four new friends help make this new life a little easier. Read on for kittens, sleep overs, and so much more fluffy goodness!

Barely 5 minutes out of his 8-month coma, Tadashi Hamada has already observed three very important things- 1. he was not in San Fransokyo 2. there was a new group of superheroes in town 3. The group was made up of his friends, the healthcare bot he created AND LEAD BY HIS LITTLE BROTHER. AU where Tadashi lives, but the rest is pretty much canon.  (Rated T for language later on)

The college party at Fred's went completely wrong. Someone spiked the punch, and both Hiro and Gogo had to pay for the deep consequence of their actions. But can they really call an innocent child, a mistake? NOW COMPLETE! 1st of Welcome to the family series.
