You talk like Riolu has prior knownledge about that though. Also, can you show me where Riolu has even read minds? I do not remember that.
These may be relevant:
Mind Reader: The user senses the target's movements with its mind to ensure its next attack does not miss the target.
Also, Pokedex entries:
| Platinum | It has the peculiar power of being able to see emotions such as joy and rage in the form of waves. |
|---|
| Omega Ruby | It uses the shapes of auras, which change according to emotion, to communicate with others. |
|---|
| Sun | It can discern the physical and emotional states of people, Pokémon, and other natural things from the shape of their aura waves. |
|---|
| Legends: Arceus | Though infantile in appearance, it has the mysterious ability to read the minds of humans. The pure of heart are met with Riolu's approval, while those of ill nature earn only its loathing. |
|---|
| Scarlet | They communicate with one another using their auras. They are able to run all through the night. |
|---|
Again, Hundreds of Meters of range versus over 300 meters per second in Speed Equalized.
Plus, physical attacks are not that good, given that Ness can create shields which can reflect or lower the damage of physical attacks, meaning that Melee combat definitely is not a good option here.
Shape of the shields?
Because if they don't encompass Ness's whole body, they can be maneuvered around.
Also, Riolu has a move for that:
Feint:
This attack can hit a target using a move such as Protect or Detect. This also lifts the effects of those moves.
If there's a barrier, Riolu can simply punch through it with that move. In gameplay, it's heightened priority as well, so Riolu may be moving faster than usual, too, when using this, similar to Quick Attack.
And? It does not change that he's still a playable character with a pre-set leading move. My point still stands.
It is not pre-set, Ness has his own personality that'd influence how he'd lead.
He's been shown to get homesick for his family, give to those in need, selflessly sacrifice himself for others, remember the fallen (Flying Men), & even want to be friends with a mortal enemy like Porky, as well as name his PSI Rockin after his favorite thing.
So PSI Rockin would be his opening move if anything, given he named it for his favorite thing.
As opposed to going for PK Flash as a No Mercy One Hit Kill, when Ness is still in-character & would probably rather knock out or drive away this hostile animal-like creature, no?
I dunno here kek. What I mean is that Ness has more ways to end the fight quickly than Riolu does.
The problem is that PK Flash is only debilitating less than half the time, when it inflicts instant death AND doesn't get Endured or dodged via Detect.
Or copied by his faster opponent, causing Ness to get one shot again because he doesn't resist any of PK Flash's hax, except WITH like, 2 of the Optional Items he could be wearing & we don't even know if Optional stuff is present.
The other half of the time, Riolu just aims bad because Numbness -& aiming bad doesn't matter if it's choosing to use a set-up move at that time like Agility, Iron Defense, etc.- or inflicts Crying, which can be ignored because Riolu regularly uses Aura to see beings via emotions & can read minds. It'll know where Ness is.
& as said, if Riolu is using set up like Agility, Iron Defense, Swords Dance, Nasty Plot, etc. it is doing so faster than Ness is doing his moves, even more so if it uses Agility.
Not to mention Riolu's aura gets bigger, likely meaning stronger, when it gets afraid or sad.
& as ineffectual as Crying is, it's EQUALLY as likely as Instant Death, at 37.5%.
& Riolu decides it likes what PK Flash, Prankster means its faster when using Copycat. So Riolu can spam PK Flash faster than Ness can to roll on that more often.
So how do we know its involved, allowed & applicable in this match.
3 Swords Dances or 3 Nasty Plots & Riolu is 2.5x stronger than Ness. Considering its faster when not using attacking moves, can make itself faster, can read his mind (So it'll probably know if this unfamiliar hostile human is thinking "I need to try to one shot this monster".), has better Stamina, & has multiple moves to ensure survival, I think it can find opportunity.
Also, if it comes to melee combat, Riolu can use Counter &/or with Endure first to deliberately take a hit & then strike back with twice the damage dealt to it.
There's also Reversal, which gets a massive power boost at low Stamina.
In the anime term:
bulbapedia.bulbagarden.net
Galarian Farfetch'd appears, effortlessly faints Goh's Kantonian Farfetch'd when both of them use Night Slash
Ash sends out his recently trained Riolu, orders Vacuum Wave, the Farfetch'd blocks it.
As the Farfetch'd readies another Night Slash, Ash has Riolu use Force Palm. Said Farfetch'd takes the attack, charges in.
Ash has Riolu use Double Team Night Slash is evaded.
Riolu bombards Farfetch'd with a flurry of Vacuum Waves, dispelling the copies & hitting the real Riolu.
Ash has Riolu use Reversal, it hits, Farfetch'd is standing for a bit, but then faints.
That Farfetch'd one-shot a trained Farfetch'd that should have nearly been its equal, face-tanked & ignored Riolu's prior attacks, despite wild & despite Riolu being trained, it was arguably the superior up until then.
Yet Reversal at low Stamina fainted it.
Said Farfetch'd was later caught by Ash, & both it & his Riolu were later evolved, & later still became part of Ash's Champion team. So I'd say that Farfetch'd was at least of above average capabilities, considering what it achieved.
Reversal at low Stamina was also how Ash's Lucario finished off Cynthia's Garchomp.
& in gameplay terms, its base power varies from 20 to 200.
So yeah. Low Stamina Reversal is somewhere between:
1. "Strong enough to near one-shot something strong enough to ignore & tank all Riolu's other attacks that could also one shot a member of almost the same species (Galarian & Kantonian regional difference) that was using the same move & near oneshot Riolu itself"....
& 2. Up to 10 times stronger, if we go by base power. If we did, 0.62 * 10 = 6.2, versus Ness's 1.1.
If Ness does tank that, he'll be in bad shape, & if Riolu needs to do another one, it can outspeed Ness's healing with Quick Attack, Vacuum Wave (Ranged as well.), Copycat (2 Reversals in a row.), or Feint.
Also that 0.62 isn't accounting for any modifiers from IQ Skills, nor is it accounting for that Riolu can add 100% of base with a single Swords Dance, Iron Defense, Agility or Nasty Plot; After a single Swords Dance or Nasty Plot, Riolu has higher AP (For the relevant offense.) & can often be faster (Due to Prankster & Priority moves, not to mention Agility.), after a single set-up move.
What is the thing that matters is that killing is not an option here.
Well, Pokemon cause one another to faint plenty often, & Riolu can see aura which is life energy, & it's probably not evil.
It can go for knocking Ness out.
Besides... I have no idea why the Opional Equipment is listed as Standard in that section, ngl.
CRT material?
