@BCTheEntity Alright, I approve the character.
3. I mean... when I say absurd, I mean really a whole hell of a lot of power is gained from Namekian fusion. Nail had a power level of 42000, and Piccolo presumably didn't have much more than that, if he wasn't in fact weaker; yet their fused state escalated Piccolo's power level to more than a million, most likely at least 1.2 million or so given the difference between how he does in his fights against Frieza's second and third forms. Even if we assume that Piccolo miraculously reached a PL of 58000 from his sub-Nappa strength prior to death whilst training with King Kai to round off the combined PL of him and Nail to 100000, that's still a twelve times multiplier on that amount of power, minimum, and it's far more likely that their combined PL was closer to 50000, requiring a multiplier of twenty four times to reach the 1.2 million minimum (lets assume the PL of fusing Namekians is added together prior to the multiplier itself), and probably twenty five times if we assume both the initial combined PL and the fusion multiplier are relatively round numbers. Piccolo's fusion with Kami was presumably a less dramatic boost than that, but given how much weaker Kami was than Piccolo at that stage, and the fact that Piccolo was already a fused being (suggesting reduced potential in future fusions), it'd still have been pretty impressive. Long story short, even the lowest possible combined PL between Harkon and Limic, 950, would likely have resulted in a PL of just under 24000, and the higher number of 1150 would have given even more than that, nearly 29000. In short, Harkon's far too weak for a fused Namekian.
4. ...I mean, maybe? I'm just saying, one clean hit with even a single shuriken could probably take any human-sized target's head off, and it doesn't seem like it takes much time to create one. I'd have figured the actual difficulty in the technique isn't in the amount of ki you put in, but in the way it's spun to form a razor edge, presumably with most of the disc's ki focused at that edge, which is why they're always made to be so large in canon - you may as well make it as likely to hit as you can get, especially since the disc always seem to be going at a fair clip (not the Final Flash's "across the galaxy and blowing up a distant planet in a few seconds" fast, but not overly slow either), and since one can figure out ways of telekinetically manipulating any given disc.
5. Maybe Guru's powerup unlocked Dende's native potential for magic, and Healing just happened to be the field he was naturally skilled in. Maybe his potential unlocking ability had two different types, with the magic type only working on beings with the potential for magic, i.e. not most humans or Saiyans, and certainly not those with a generally martial inclination. Or it just changes what it does depending on what significant potential it senses within any given being. My point is, there's a few possible reasons why Dende suddenly acquired healing abilities, and since he didn't show any potential in ki usage either before then, I have trouble imagining that he had "special ki" which needed its potential unlocking when there's clearly a precedent for magical healing, both in-series and in this game.

1. There's no way Piccolo got to 800000 from 3500 in less than two months, when Goku only increased from 8000 to 90000, with a zenkai boost and after training at one hundred times Earth's normal gravity practically non-stop for six days. That being said, yes, it's totally feasible that Limic's corruption might have affected the fusion in some way, though I feel like it might not need to be the case that Harkon doesn't then improve his power at all after fusing with him. That just seems incongruous to how DBZ itself works; even the weaker characters improve fairly consistently as long as they keep training to improve their power level, after all.
2. Well, of course. All I'm saying is that it's a pretty major thing to need to account for, if a character has a cuts-nearly-everything attack that they can basically spam freely.
3. Oh right, he could do that. Even so, I'd still go with the thing that has a precedent in canon over the thing that doesn't, as a general rule.
