IiSaiMomo

IiSaiMomo is the poly ship between Tenya Iida, Saiko Intelli and Momo Yaoyorozu from the My Hero Academia fandom.

Tenya and Momo are the 's representative, both have the strict but yet caring nature for their classmates. Both of them are also the 'rich kids', because they're coming from a respective wealthy family, but yet they technically never brag about it (They brag without even realizing it. Momo a few times shown her classmates about her family's wealth without really realize that her classmates are pretty jealous, but they let it slide because she's cute when they're talking about that meanwhile Tenya is when he told Ochako in BNHA Smash!! that his family also contributes in a Gym's service), but even though Tenya is from a family full of heroes, he stills get into UA not through recommendation entrance exam, but the regular entrance exam.

Saiko and Momo met in, trying to defeat her and her classmates to get points from them, but failed (With a close victory). When the Class 1-A students leave the room to find Momo's plan was successful, Saiko hides behind the door and then locks herself and Momo back inside the room. Saiko admits she's surprised Momo would go with such a high-risk tactic rather than the predictable route. Momo can't move as well from overusing her Quirk and Saiko tries to tag her targets to make her fail. Momo counters by handcuffing their arms together. She buys enough time for Mezo to break down the door. Tsuyu rushes in and uses her tongue to restrain Saiko's other arm. Saiko is shocked that Momo's allies came to her rescue because they could've passed without her. Kyoka, Tsuyu, and Mezo explain that they would never leave their friend behind and Momo follows up by saying that's just how Class 1-A is. Impressed by the Momo and her classmates, Saiko admits defeat.

Tenya and Saiko never met in canon, but both shared similar personalities like their confidence in leading their peers, both are full of themselves too (But Tenya punishes himself after he realizes that he's being full of himself, Saiko don't). But although Saiko got a high IQ, her EQ is rather low, as shown when she questioned why Tsuyu, Mezo and Kyoka had come back to rescue Momo, when it could have likely been that their friend had already been eliminated; they should have been worrying about themselves instead. Having humbly acknowledged her loss, however, she seems to realize that not all people base their actions on sheer logic and selfish tendencies. Meanwhile Tenya have a pretty high EQ, shown in him going with Izuku, Momo, Shoto and Eijiro to save Katsuki.
