We don't really know how strong Rimiru was before he got degenerate.

@Nicholas8293

Rimaru in his/their early days was given a name by the Storm Dragon Veldora (a monster getting a name in that world is a big deal, gives you a huge power boost, maybe even evolves you) and has absorbed several monsters he’s encountered and killed (Spider, Lizard, Snake, Centipede, Bat and Dire Wolf.)

Without the Master Emerald Boost, Anti-Sonic is just a Warped Mirror Varient of Pre-SGW Archie Classic Sonic, so I assume he would have some of the same powers as him!

Yea, but that doesn't really explain their power. i don't follow anything sonic, so idk his power.
