Nikoleos's childhood is pretty much of him being all big and fat. Many of his friends (except Genos) called him "the big leo Nikoleos" by his overall appearance. One of his friend Marlene, a popular girl came only to laugh by his appearance (plus she did more abuse than everyone else in thw school), he's pretty shy and not pretty confident about his body back then.

10 years later when Nikoleos have big changes, the girl who abuse her seems to forgot who is this big lion. Nikoleos still remember her face pretty well and tell her that he is "the big leo Nikoleos" himself. While Marlene seems different than before, she forgive of what she did to him in the past. Luckily, they have a great time hanging out together.

What a lovely re-union, despite the changes :D
