[@bushidoxisamu2] to make things easier for you here’s a list of some characters based off their relative power.

Sigurd: Unpowered/Very- Low powered 

Isaac the Ghoul: Low powered

Clockwork Man: Mid – Powered (Lower side)

Anna: Mid Powered

Higan: High-Mid Powered

Fury: High Powered

There ya go, feel free to fight any of those, or any other characters you see on my list.

Or if you'd prefer it in the old tier system (which most of my characters roughly follow.)

Sigurd: 2/3
Isaac: 3
Clockwork Man: 4
Anna: 5
Higan: 5/6
Fury: 6
