Henrietta Universe - Weak, the only beings that are very strong there are Omnikoth and Henrietta. You'd kinda expect this from a universe made to be pure. (however, that might change as development goes on)

Adventerror Universe - Pretty damn strong. Almost everything there can put up a good fight. A lot of people have magic and powers, and are willing to use those on you, little hesitation.

TAS Universe - You need to be ready if you want to go there. It doesn't have much rules, unlike the Adventerror and Henrietta Universes. Almost everything is super powerful there, some things have multiple forms, some have various powers, and you can never really know what you'd find there.

Redacted Universe - The second strongest universe. You barely know what you can find there, and what is going on there in general. It is extremely dangerous, and only people who are truly ready can enter.

Lionason Universe - The strongest universe. You can literally just stumble upon gods who will delete you because of your opinions, and there is also intense war. Almost everything there is as powerful as Sans, minus the 1HP. When entering, be, ready. Otherwise, you will die there.
