To add some information to the first comment:
The character first appears in Season 2, Episode 12.
His name is Jared, and the protagonist in question is Musa.
He reappears in the final episode of Season 2, but he doesn't interact with Musa.
2 characters pretend to be each other for most of the first season. Also one of the characters finds out they're adopted. One character is made to belief their destiny is to be a horrible person.
In Season 2, the main antagonist (Lord Darkar) can shapeshift into a snake.
In Season 3, ice snakes live in the Omega Dimension, a planet used as a prison.
This is what Enchantix is all about, with Tecna being believed to be dead and Flora temporarily drowning before the magic river she drowned in reversing time and bringing her back.
Musa's Mother passed away when Musa was quite young. This happens pre-season 1 but is talked about occasionally, with ot being taked about the most probably in Season 2 Episode 15. It is mentioned occasionally throughout the show.
Musa and Riven seem to have mental health struggles due to childhood trama, Musa loosing her mother, Riven neglect/abandonment. These struggles also effect their relationship
No, no one is shown to have an eating disoder and are not drawn to be underweight or overweight in relation to the artstyle
Stella is shown to be a bit overweight as a child in flashbacks in s3
In season 4, the protagonists cause a few crashes on intersections for being in the road. None of the known characters are involved and nobody is shown to be hurt.
In season 3, one of the characters almost drowns to death in a river to save her sister. She survives and is completely okay afterwards, but the scene is quite distressing.
