After he got out of the hospital and went home
Zen found himself a letter saying:
I Got your mother..
Come to (Adress) and be ready

Zen was furious and packed up his stuff
villain attacks are not rare, but Zen can't help ,but go
being a 18 year old teen without power.

It looks hopeless for him and this dangerous magical world,but he have the strongest symbiote in his body

That symbiote name is stayn
also known as the manifestation of strength

After getting his ass beat by the villain Zen call Stayn for help
The Rest is up to Stayn
