Super Smash Bros. Ultimate introduces innovative fighter mechanics, and the duo from Xenoblade Chronicles 2, Pyra and Mythra, exemplifies this with their seamless swapping feature. Right in the character select screen (CSS), players can toggle between them using the Y button, allowing instant access to either form before a match begins. This guide explores everything from basic selection to advanced gameplay strategies, ensuring you harness their full potential.
Navigating the Character Select Screen Basics
The CSS in Smash Ultimate serves as the gateway to battles, where fighters are chosen via a grid of portraits. For multi-form characters like Pyra/Mythra, the interface stacks them uniquely, sharing a single slot similar to Zelda/Sheik in past titles. Upon highlighting their icon, the default starts as one form, but a quick input changes it without navigating menus.
- Highlight the slot: Move to Pyra/Mythra’s position using the D-pad or analog stick.
- Press Y: This toggles between Pyra (power-focused) and Mythra (speed-oriented).
- Confirm with A: Lock in your choice and proceed to stage selection.
This Y-swap mirrors controls for Pokémon Trainer, streamlining picks for players familiar with those mechanics. It’s active in modes like Vs. Mode, Tourney, and Quickplay when echo fighter stacking is enabled. Experimenting here lets you preview forms without committing, vital for adapting to opponent lineups.
Pyra vs. Mythra: Core Differences at a Glance
Pyra and Mythra aren’t just cosmetic variants; they offer distinct playstyles. Pyra emphasizes raw power with slower, heavier hits ideal for kill confirms, while Mythra prioritizes agility for combos and pokes.
| Aspect | Pyra | Mythra |
|---|---|---|
| Mobility | Slower dash/walk, poor air speed | Fast dash, excellent air mobility |
| Damage Output | High per-hit damage, strong smashes | Lower per-hit, excels in racking via combos |
| Recovery | Prominence Revolt: Vertical rise, quick drop | Ray of Punishment: Boost with follow-up |
| Best Use | Kills, edgeguards | Neutral, juggling |
This table highlights why CSS swaps matter—pick Mythra against aggressive foes for evasion, or Pyra for patient punishers. Their shared slot demands pre-match decisions based on matchup knowledge.
Mid-Match Swapping: The Down-B Mechanic
Beyond selection, their Down Special enables fluid switches anytime, even mid-air or during momentum. This “Swap to Pyra/Mythra” is quicker than Pokémon Trainer changes, preserving speed for evasions akin to a second dodge. Voice lines add flair: Pyra calls “Switching!” to Mythra, who responds “Right here!”.
In practice, swap defensively offstage or to extend combos. For instance, Mythra’s down tilt into up tilt, then swap to Pyra’s aerial for amplified damage. Videos show swapping post-juggle to punish get-up options, retaining airdrift for unpredictability.
- Start as Mythra for neutral control.
- Swap to Pyra when cornering opponents.
- Revert to Mythra for recovery or stage control resets.
Strategic Playstyles for Competitive Edge
Mastering Pyra/Mythra requires blending their strengths. Begin matches with Mythra to win neutral—her Photon Edge side-B pressures shields, and Lightning Buster neutral-B punishes approaches. Once foes are damaged (60-80%), switch to Pyra for smashes that KO early.
Offstage, Mythra’s superior recovery shines: reverse her up-B for horizontal distance, then follow-up. Pyra suits aggressive edgeguards but risks self-destructs due to fall speed. Juggle with sword range—Mythra’s up tilt flames confuse, chaining to Pyra’s Prominence Revolt.
Matchup tips: Against fast zoners, Mythra evades projectiles; versus heavies, Pyra’s range dominates. Tournaments favor adaptive swapping, as seen in pro play where mid-combo shifts disrupt reads.
Customizing Looks: Palette and Fighter Sync
Post-selection, eight costumes await, blending Pyra’s red and Mythra’s silver tones. Edit via the CSS customization menu, swapping hair, crystals, and accents. Sync rules apply: if opponent picks a Xenoblade fighter, colors auto-adjust for distinction.
Creative palettes evoke their lore—silver hair for ethereal Mythra variants or fiery reds for Pyra dominance. These visuals enhance immersion without affecting stats.
Advanced Tactics and Combo Extensions
Swapping elevates combos: Mythra’s quick tilts into Pyra’s powerful aerials yield 30-40% strings. Offstage reads—Mythra damages, swap to Pyra for spikes. Against ledge campers, Mythra invades safely, Pyra finishes.
Frame data reveals swaps at 10-15 frames, outpacing interruptions. Practice in Training Mode: set CPU to aggressive, cycle forms to internalize timings. Online, bait swaps to fakeout opponents expecting patterns.
Common Pitfalls and How to Avoid Them
New players over-swap, losing momentum—stick to one form per exchange unless extending. Pyra’s sluggishness invites juggling; swap preemptively. Ignore voice cues at first; focus on inputs for consistency.
- Avoid Pyra early-game; she’s punishable.
- Don’t swap during kills—commit power.
- Master ledge options per form.
