Cloud Gate → Aon Center

DBSCAN at eps=200m, min_samples=3 identifies a single density-connected cluster spanning Millennium Park east into Lakeshore East. 8 gyms in a 378 m diameter footprint, 7.3 minute walk from Palmer House Hilton. North of Monroe Drive — outside the restricted park zone, accessible every day of the trip.

The Super Mega Raid Playbook

The highest-priority 30 minutes of the trip. Niantic spawns new 1,000-trainer-capacity gyms during the final 30 minutes of each park session. Both Mega Mewtwo X and Mega Mewtwo Y appear. Catches come with the Pokémon GO Fest 2026 location background and the first Mega Level pre-unlocked.

Pre-positioning · 5:00 – 5:29 PM

• Be at your designated Gym (assigned to ticket holders by email in advance) by 5:25 PM — you cannot freely pick a gym on the day. Confirm the assignment from the email + in-game News before the session.
• Mega Gengar strongly recommended evolved upon park entry at 2:00 PM (Ghost/Poison · boosts the Ghost squad +30% against both X and Y). Lasts 8 hours, so 2 PM evolve covers the 5:30 PM raid. Niantic has NOT published any normal Mega Raid lineup for the park experience — don't plan to grind Mega energy during the session. Evolve from stockpile energy on entry. Mega Tyranitar or Mega Houndoom only if running Dark squad for Mewtwo Y — but Mega Gengar covers both forms.
• 🛡️ It's a Unity Raid = Super Mega Raid, WITH shields (corrected): Mega Mewtwo starts with multiple shields (reported ~10) that dramatically cut damage and are broken only by Charged Attacks from a Mega-evolved Pokémon — each trainer breaks one. So an active Mega genuinely matters: keep Mega Gengar evolved (it also gives the +30% Ghost boost). The earlier "no-shields Unity Raid" reading was wrong.
• 🆕 Unity Attack — phone overhead at the finishing window. The raid's KO move is a collective "raise your phone in the air" gesture. Arm-fatigue risk for the apex 5 minutes; brace against your body or use a hand strap. Make sure the MagCooler clip doesn't interfere with the orientation sensor.
• 🆕 Expected energy payoff: ~900 Mewtwo Mega Energy from the park session (~450 per Unity Raid completion × X + Y, per post-Tokyo reports; Niantic only says "a large amount"). Plus the catch with Mega Level 1 (sometimes 2 or 3) unlocked. Chicago→Global gap is now a much shorter walk to Mega-evolving subsequently.
• Phone battery ≥70% · brightness low · Battery Saver ON · AR Plus OFF.
• Golden Razz Berries and Ultra Balls confirmed in inventory.
• Counter teams healed and revived.

At 5:30:00 PM

• Go to your designated Gym; 1,000-trainer capacity = expect server lag. Fire a Charged Attack from your Mega to break your shield when prompted.
• Tap to join the lobby immediately. Do not wait for fill — it will fill regardless.
• If both forms spawn, run the closer one first, then relobby for the other.
• Mega Mewtwo X (Fighting/Psychic): Ghost only. Mega Gengar (Shadow Claw + Shadow Ball or Lick + Shadow Ball), Chandelure (Hex + Shadow Ball), Shadow Banette / Mega Banette. Dark is neutral on X (Fighting resists Dark: 1.6 × 0.625 = 1.0); Hydreigon and Shadow Tyranitar underperform.
• Mega Mewtwo Y (pure Psychic): same Ghost squad works; Dark also viable for Y only. If running Dark on Y, pair with Mega Tyranitar or Mega Houndoom for the Dark mega boost — NOT Mega Gengar.

Catch screen

• Mega bosses have ~2% base catch rate.
• Golden Razz raises catch rate ~2.5x. Always use.
• Excellent + curveball = ~4x multiplier. Practice on common Mewtwo first.
• Expect 9–12 premier balls per raid (Best Friend bonus + Mega bonus + damage contribution).

Mewtwo by Moveset

Doctrine: Ghost-led, not Dark-led. Mega Mewtwo X is Fighting/Psychic; Fighting resists Dark (0.625×), so Dark damage on X is neutral (1.6 × 0.625 = 1.0). Ghost is super-effective on all three Mewtwo forms (X, Y, regular) AND gets the +30% mega boost from Mega Gengar's Ghost/Poison typing. Dark is kept as backup for Y / regular Mewtwo only, where it works but requires a different mega (Tyranitar/Houndoom) for the boost.

Target counter team (build by Jun 4)

Ghost-led primary build. The Feb 2026 Mega update boost is +30% to attacks matching the active Mega's type, +10% to all others (flat — it does NOT scale with Mega Level), so Mega Gengar's Ghost/Poison typing gives every Ghost attacker on the bench +30%. Dawn Wings Necrozma (Psychic/Ghost) is the standout non-Mega attacker — it resists Psystrike (0.625×) and stays full SE on all three forms. Chandelure and Banette take Psystrike at neutral — whereas Mega Gengar takes it super-effectively (1.6×, via its Poison side), so it's the glass cannon: top DPS, but keep it healed.

Lobby Fill Playbook

Two ways to fill a 5★ Mewtwo lobby as a solo player.

1. Physical density — stand where 30+ raiders are standing. Cloud Gate cluster during GO Fest week always fills in <2 min.
2. Remote invites — your friends list. Start the raid, invite 5 Best Friends, fill the remaining 4 slots from walk-ups. Mewtwo is not a Shadow boss in this event, so remote invites work.

Pass deployment rule

• Never decline a 5★, Primal, Shadow 5★, or Mega Mewtwo raid for cost reasons.
• Skip 1★ raids unless on the way and shiny-eligible.
• Skip Tier 3 raids during active 5★ / Primal / Shadow windows. Exception: Paldean Tauros (Blaze Breed) shiny (ticket-holder boosted) — always raid.

The math of "pass supply is irrelevant"

  400 stockpile          (premium passes)
+ 18/day × 4 days = 72   (Raid Lover free passes)
+ ~10 park session       (in-park free passes, Saturday only)
─────────────────────────
  ~482 total available · 320+ raid target (80/day × 4 days)
  · margin of ~160 passes for replays / overflow

Restricted Zone Logistics

The Grant Park interior is closed to non-ticket-holders during the event. Buckingham Fountain and the Hutchinson Field staging area are inside.
