Can you explain exactly how does this work?
That sounds really OP. Even a 3-A attack cannot harm him in this case? Sounds like she cannot hurt him no matter what.
First of all...Yeah there's probably SOME level of NLF, but we've definitely seen it absorb damage within ballparks and one-shots, so likely applicable here. (also would you believe 'Negation of Absorption' is a common ability in-universe for this exact reason? ...PAD gives a LOT of characters 'Power Null, lol' to solve problems they create...)
I'm also prefacing this with: PAD is stupid and made really dumb writing decisions.
PAD is a match-three puzzle game where you link the colorful orbs on the screen to power up characters, matching multiple 'chains' lets characters work together, link attacks, and increase their power with 'Combos'. However certain abilities like 'Phoenix Knight's Soul' allows the user to absorb the damage rather than taking it if a certain combo threshold isn't met with attacks. Hit them with a combo too small? You've healed them and done nothing. Hit them with a high enough combo at once, you break through and deal actual damage.
So, again...This sounds game mechanic-y. We used to disregard these abilities as game mechanics. However PAD made the baffling decision to include characters directly explaining their 'combo absorber' abilities, and a plotline where characters go to an actual school to learn about Combos and how to use them in these situations. So...It's a very, very, very dumb but canon thing.
Again, some amount of NLF has to be in play here that a character ridiculously stronger than Homura would one-shot him and disregard this system, but Lizardy's probably not in that threshold since the gap is a oneshot but not any moreso than we sometimes see in-universe? So she's in a awkward situation here where she needs to realize that hitting him 4 or less times or him 'breaking the combo' by dodging or something along those lines isn't working, but 5 and more will do actual damage. ...But also, Homura will be using some invisible thought-based force she can't see to ALSO heal, which might make forming a strategy confusing, since Homura's ability to heal and tank fatal blows likely won't make sense initially. Sometimes he heals by being hit, sometimes he doesn't, and sometimes he heals for literally no reason, at least from her perspective.
But Lizardy's not dumb. She's smart, it's clearly listed in her intelligence her strategic abilities are her strength, and she's favoring a flying AND swarming fighting style. Once she figures this out, there's a clear opening there to take Homura out. Land the right combos...Twice in a row. She needs to do that while denying Homura the freedom to heal (because Homura
could get unlucky and there be a lack of Heal Orbs when he needs them) or dodge or destroy incoming parts of hers to stop their next attack or find some way to abuse his combo of abilities to preserve his life. The moment she does and Homura slips up, she absolutely could clinch that sweet spot and destroy him.
That's why I'm not confident in where my vote should be anymore. Lizardy's very smart and has a massive AP lead and has mobility and swarming to chase Homura down...But Homura's going to be a weird opponent because PAD can be...weird. What's keeping him alive is a combo of powers that are not very conventional...
