Bio: Heinrich was an average man that moved to the Celestials community living a regular quiet life. But one day while walking through in Nebula City, he saw Dasha standing in the middle of the street showing her large naked body to the public. He approached Dasha, but Dasha was shocked and suprised because other men are too intimidated by her. But he wasn't. Dasha quickly liked Heinrich and he liked her. After many dates and Dasha breaking up with her boyfriend (Eirik), her and Heinrich became a couple. But a few weeks after dating, Dasha did not like that Heinrich was small and an average man. She had an idea in how to fix him and it involved her lab.

Dasha carried Heinrich to her giant underground lab while Heirich was riding her left nipple. Dasha injected many experimental serums to him, told him to get inside a gas chamber, and she released the titan gas that changed him into a giant muscular male titan. After the lab experiment, Heinrich went from being an average 5'10" male to a 10 foot tall muscular titan. Now that Heinrich and Dasha are the biggest humans in the Celestials community, they are the perfect giant couple.
