The slow beat doesn't change the fact they have filled the screen and created massive words each one. The danmaku she has faced is. It better or at least on par, and definitely better when considering clones. Training several others doesn't mean she can suddenly fight danmaku from multiple sources at once. We have no context on how she did it, if she even did it all at once, and if she even faced danmaku while doing it. She hasn't faced that. She has faced danmaku from one source. Not from multiple sources on multiple angles. She is going to be getting hit a lot and doing very little of any hitting at all, and regen can easily cover if he takes too much damage. Teleports to regen. And she has no way to stop him, and had to actively find him as well
Yes he is better mobile. He can literally fly. That's better mobility than Undyne who can't fly and can't prevent him from flying. She can't prevent movement either. So yes, he is better mobile
Undyne has what is a almost not even real AP advantage, and skill. And she has no answer to keeping ringo in one spot. Ringo Resisting her green mode, plus having power she hasn't faced before is a really bad position for her. Even taking on one ringo is hard enough due to teleportation, Danmaku, large attacks and AOE, and his smaller regen. His attacks also provide a large defense as their sheer size and basically same AP would be capable is stopping her onslaught of spears.
And I checked it. She has a 1.035485250106883 AP advantage. That's nothing
Ringo is going to be getting hit far less, can heal from getting hit, can give off far more attack, and the difference in power is basically nothing. She tries fighting even one ringo, and that ringo has Danmaku that can block her attacks and damage her, teleportation to dodge attacks and get out of site for surprise attacks, flight for mobility, and regen to heal if he takes some damage. Now add in clones and it's a certain death for Undyne
